Search Engine Super Hero

If you are working on a project with lots of data in your database, this post is worth reading. All we will talk about how to use a bulk of data ( here bulk means really bulk ) to make a useful search engine.

Here I will share my experience of Elastic Search and how to set up and get going with it.

So we will start with WHAT:

Elastic search can be defined as the hub of data that stores data in such a manner that it is always easy to search and fetch the data from it. It is done using indexing and some other concept which we will discuss in this post.

Elasticsearch is the distributed search and analytics engine at the heart of the Elastic Stack. Logstash ( Server-side data processing pipeline ) and Beats ( Open platform for single-purpose data shippers ) facilitate collecting, aggregating, and enriching your data and storing it in Elasticsearch. Kibana enables you to interactively explore, visualize, and share insights into your data and manage and monitor the stack. Elasticsearch is where the indexing, search, and analysis magic happens.

Elasticsearch provides near real-time search and analytics for all types of data. Whether you have structured or unstructured text, numerical data, or geospatial data, Elasticsearch can efficiently store and index it in a way that supports fast searches. You can go far beyond simple data retrieval and aggregate information to discover trends and patterns in your data. And as your data and query volume grows, the distributed nature of Elasticsearch enables your deployment to grow seamlessly right along with it.

While not every problem is a search problem, Elasticsearch offers speed and flexibility to handle data in a wide variety of use cases:

• Add a search box to an app or website
• Store and analyze logs, metrics, and security event data
• Use machine learning to automatically model the behavior of your data in real-time
• Automate business workflows using Elasticsearch as a storage engine
• Manage, integrate, and analyze spatial information using Elasticsearch as a geographic information system (GIS)
• Store and process genetic data using Elasticsearch as a bioinformatics research tool

We’re continually amazed by the novel ways people use search. But whether your use case is similar to one of these, or you’re using Elasticsearch to tackle a new problem, the way you work with your data, documents, and indices in Elasticsearch is the same.

Создание фильтров поиска и товаров с помощью Javascript

Добро пожаловать в сегодняшнее руководство. В сегодняшнем руководстве мы узнаем, как создавать фильтры и искать товары. Для создания этого проекта нам понадобятся HTML, CSS и Javascript. Поскольку это довольно продвинутый проект, я бы не рекомендовал его новичку в javascript. Если вы средний уровень или эксперт в javascript, вы определенно можете сделать это.

Давайте посмотрим, что это за проект на самом деле. В проект входит серия карточек продуктов. У каждой из этих карт есть название, цена и категория. Над этими тегами находится панель поиска, где пользователи могут искать продукт по его названию.

Под панелью поиска находится группа кнопок. На каждой из этих кнопок есть название категории. Когда пользователь нажимает любую из этих кнопок, будут отображаться продукты, соответствующие этой конкретной категории.

Структура папок проекта:

Теперь давайте сначала создадим структуру каталогов проекта, чтобы мы могли начать кодирование. Начнем с создания папки проекта с названием «Фильтры и поиск продуктов». Внутри этой папки мы создаем три файла. Первый есть index.html, второй есть style.cssи третий есть script.js. Эти файлы представляют собой HTML-документы, таблицы стилей и файлы сценариев соответственно.

HTML:

Начнем с HTML-кода. Сначала скопируйте приведенный ниже код и вставьте его в свой HTML-файл.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Product Filter And Search</title>
    <!-- Google Font -->
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500&display=swap"
      rel="stylesheet"
    />
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="wrapper">
      <div id="search-container">
        <input
          type="search"
          id="search-input"
          placeholder="Search product name here.."
        />
        <button id="search">Search</button>
      </div>
      <div id="buttons">
        <button class="button-value" onclick="filterProduct('all')">All</button>
        <button class="button-value" onclick="filterProduct('Topwear')">
          Topwear
        </button>
        <button class="button-value" onclick="filterProduct('Bottomwear')">
          Bottomwear
        </button>
        <button class="button-value" onclick="filterProduct('Jacket')">
          Jacket
        </button>
        <button class="button-value" onclick="filterProduct('Watch')">
          Watch
        </button>
      </div>
      <div id="products"></div>
    </div>
    <!-- Script -->
    <script src="script.js"></script>
  </body>
</html>

CSS:

Далее, чтобы добавить стили в этот проект, мы используем CSS. Теперь скопируйте приведенный ниже код и вставьте его в свой файл CSS.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  border: none;
  outline: none;
  font-family: "Poppins", sans-serif;
}
body {
  background-color: #f5f8ff;
}
.wrapper {
  width: 95%;
  margin: 0 auto;
}
#search-container {
  margin: 1em 0;
}
#search-container input {
  background-color: transparent;
  width: 40%;
  border-bottom: 2px solid #110f29;
  padding: 1em 0.3em;
}
#search-container input:focus {
  border-bottom-color: #6759ff;
}
#search-container button {
  padding: 1em 2em;
  margin-left: 1em;
  background-color: #6759ff;
  color: #ffffff;
  border-radius: 5px;
  margin-top: 0.5em;
}
.button-value {
  border: 2px solid #6759ff;
  padding: 1em 2.2em;
  border-radius: 3em;
  background-color: transparent;
  color: #6759ff;
  cursor: pointer;
}
.active {
  background-color: #6759ff;
  color: #ffffff;
}
#products {
  display: grid;
  grid-template-columns: auto auto auto;
  grid-column-gap: 1.5em;
  padding: 2em 0;
}
.card {
  background-color: #ffffff;
  max-width: 18em;
  margin-top: 1em;
  padding: 1em;
  border-radius: 5px;
  box-shadow: 1em 2em 2.5em rgba(1, 2, 68, 0.08);
}
.image-container {
  text-align: center;
}
img {
  max-width: 100%;
  object-fit: contain;
  height: 15em;
}
.container {
  padding-top: 1em;
  color: #110f29;
}
.container h5 {
  font-weight: 500;
}
.hide {
  display: none;
}
@media screen and (max-width: 720px) {
  img {
    max-width: 100%;
    object-fit: contain;
    height: 10em;
  }
  .card {
    max-width: 10em;
    margin-top: 1em;
  }
  #products {
    grid-template-columns: auto auto;
    grid-column-gap: 1em;
  }
}

Javascript:

Наконец, нам нужно добавить функциональность к фильтру, а также реализовать функцию поиска. Чтобы он заработал, мы добавляем javascript. Скопируйте приведенный ниже код и вставьте его в свой файл javascript.

let products = {
  data: [
    {
      productName: "Regular White T-Shirt",
      category: "Topwear",
      price: "30",
      image: "white-tshirt.jpg",
    },
    {
      productName: "Beige Short Skirt",
      category: "Bottomwear",
      price: "49",
      image: "short-skirt.jpg",
    },
    {
      productName: "Sporty SmartWatch",
      category: "Watch",
      price: "99",
      image: "sporty-smartwatch.jpg",
    },
    {
      productName: "Basic Knitted Top",
      category: "Topwear",
      price: "29",
      image: "knitted-top.jpg",
    },
    {
      productName: "Black Leather Jacket",
      category: "Jacket",
      price: "129",
      image: "black-leather-jacket.jpg",
    },
    {
      productName: "Stylish Pink Trousers",
      category: "Bottomwear",
      price: "89",
      image: "pink-trousers.jpg",
    },
    {
      productName: "Brown Men's Jacket",
      category: "Jacket",
      price: "189",
      image: "brown-jacket.jpg",
    },
    {
      productName: "Comfy Gray Pants",
      category: "Bottomwear",
      price: "49",
      image: "comfy-gray-pants.jpg",
    },
  ],
};

for (let i of products.data) {
  //Create Card
  let card = document.createElement("div");
  //Card should have category and should stay hidden initially
  card.classList.add("card", i.category, "hide");
  //image div
  let imgContainer = document.createElement("div");
  imgContainer.classList.add("image-container");
  //img tag
  let image = document.createElement("img");
  image.setAttribute("src", i.image);
  imgContainer.appendChild(image);
  card.appendChild(imgContainer);
  //container
  let container = document.createElement("div");
  container.classList.add("container");
  //product name
  let name = document.createElement("h5");
  name.classList.add("product-name");
  name.innerText = i.productName.toUpperCase();
  container.appendChild(name);
  //price
  let price = document.createElement("h6");
  price.innerText = "$" + i.price;
  container.appendChild(price);

  card.appendChild(container);
  document.getElementById("products").appendChild(card);
}

//parameter passed from button (Parameter same as category)
function filterProduct(value) {
  //Button class code
  let buttons = document.querySelectorAll(".button-value");
  buttons.forEach((button) => {
    //check if value equals innerText
    if (value.toUpperCase() == button.innerText.toUpperCase()) {
      button.classList.add("active");
    } else {
      button.classList.remove("active");
    }
  });

  //select all cards
  let elements = document.querySelectorAll(".card");
  //loop through all cards
  elements.forEach((element) => {
    //display all cards on 'all' button click
    if (value == "all") {
      element.classList.remove("hide");
    } else {
      //Check if element contains category class
      if (element.classList.contains(value)) {
        //display element based on category
        element.classList.remove("hide");
      } else {
        //hide other elements
        element.classList.add("hide");
      }
    }
  });
}

//Search button click
document.getElementById("search").addEventListener("click", () => {
  //initializations
  let searchInput = document.getElementById("search-input").value;
  let elements = document.querySelectorAll(".product-name");
  let cards = document.querySelectorAll(".card");

  //loop through all elements
  elements.forEach((element, index) => {
    //check if text includes the search value
    if (element.innerText.includes(searchInput.toUpperCase())) {
      //display matching card
      cards[index].classList.remove("hide");
    } else {
      //hide others
      cards[index].classList.add("hide");
    }
  });
});

//Initially display all products
window.onload = () => {
  filterProduct("all");
};

Теперь ваш поиск и фильтр по продукту готовы. Надеюсь, вам понравился урок.

Erstellen Sie Such- und Produktfilter mit HTML, CSS und Javascript

Willkommen zum heutigen Tutorial. Im heutigen Tutorial erfahren Sie, wie Sie Filter erstellen und nach Produkten suchen. Um dieses Projekt zu erstellen, benötigen wir HTML, CSS und Javascript. Da dies ein ziemlich fortgeschrittenes Projekt ist, würde ich es keinem Javascript-Anfänger empfehlen. Wenn Sie ein Fortgeschrittener oder Experte in Javascript sind, können Sie auf jeden Fall weitermachen und dieses machen.

Lassen Sie uns einen Überblick darüber geben, was dieses Projekt wirklich ist. Das Projekt umfasst eine Reihe von Produktkarten. Jeder dieser Karten ist ein Name, ein Preis und eine Kategorie zugeordnet. Über diesen Tags befindet sich eine Suchleiste, in der Benutzer anhand des Namens nach einem Produkt suchen können.

Unterhalb der Suchleiste befindet sich eine Gruppe von Schaltflächen. Jede dieser Schaltflächen hat einen Kategorienamen. Wenn der Benutzer auf eine dieser Schaltflächen klickt, werden die Produkte angezeigt, die dieser bestimmten Kategorie entsprechen.

Projektordnerstruktur:

Lassen Sie uns nun zunächst die Projektverzeichnisstruktur erstellen, damit wir mit dem Codieren beginnen können. Wir beginnen damit, einen Projektordner mit dem Namen "Filters and Product Search" zu erstellen. In diesem Ordner erstellen wir drei Dateien. Das erste ist index.html, das zweite ist style.cssund das dritte ist script.js. Diese Dateien sind HTML-Dokumente, Stylesheets bzw. Skriptdateien.

HTML-Code:

Wir beginnen mit dem HTML-Code. Kopieren Sie zunächst den folgenden Code und fügen Sie ihn in Ihre HTML-Datei ein.

<!DOCTYPE html>
<html lang="en">
  <head>
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Product Filter And Search</title>
    <!-- Google Font -->
    <link
      href="https://fonts.googleapis.com/css2?family=Poppins:wght@400;500&display=swap"
      rel="stylesheet"
    />
    <!-- Stylesheet -->
    <link rel="stylesheet" href="style.css" />
  </head>
  <body>
    <div class="wrapper">
      <div id="search-container">
        <input
          type="search"
          id="search-input"
          placeholder="Search product name here.."
        />
        <button id="search">Search</button>
      </div>
      <div id="buttons">
        <button class="button-value" onclick="filterProduct('all')">All</button>
        <button class="button-value" onclick="filterProduct('Topwear')">
          Topwear
        </button>
        <button class="button-value" onclick="filterProduct('Bottomwear')">
          Bottomwear
        </button>
        <button class="button-value" onclick="filterProduct('Jacket')">
          Jacket
        </button>
        <button class="button-value" onclick="filterProduct('Watch')">
          Watch
        </button>
      </div>
      <div id="products"></div>
    </div>
    <!-- Script -->
    <script src="script.js"></script>
  </body>
</html>

CSS:

Um diesem Projekt Stile hinzuzufügen, verwenden wir CSS. Kopieren Sie nun den folgenden Code und fügen Sie ihn in Ihre CSS-Datei ein.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  border: none;

  margin: 1em 0;
}
#search-container input {
  background-color: transparent;
  width: 40%;
  border-bottom: 2px solid #110f29;
  padding: 1em 0.3em;
}
#search-container input:focus {
  border-bottom-color: #6759ff;
}
#search-container button {
  padding: 1em 2em;
  margin-left: 1em;
  background-color: #6759ff;

}
.active {
  background-color: #6759ff;
  color: #ffffff;
}
#products {
  display: grid;
  grid-template-columns: auto auto auto;
  grid-column-gap: 1.5em;
  padding: 2em 0;
}
.card {
  background-color: #ffffff;
  max-width: 18em;
  margin-top: 1em;
  padding: 1em;
  border-radius: 5px;
  box-shadow: 1em 2em 2.5em rgba(1, 2, 68, 0.08);
}
.image-container {
  text-align: center;
}
img {
  max-width: 100%;
  object-fit: contain;
  height: 15em;
}
.container {
  padding-top: 1em;
  color: #110f29;
}
.container h5 {
  font-weight: 500;
}
.hide {
  display: none;
}
@media screen and (max-width: 720px) {
  img {
    max-width: 100%;
    object-fit: contain;
    height: 10em;
  }
  .card {
    max-width: 10em;
    margin-top: 1em;
  }
  #products {
    grid-template-columns: auto auto;
    grid-column-gap: 1em;
  }
}

Javascript:

Schließlich müssen wir dem Filter Funktionen hinzufügen und auch die Suchfunktion implementieren. Damit es funktioniert, fügen wir Javascript hinzu. Kopieren Sie den unten angegebenen Code und fügen Sie ihn in Ihre Javascript-Datei ein.

let products = {
  data: [
    {

  buttons.forEach((button) => {
    //check if value equals innerText
    if (value.toUpperCase() == button.innerText.toUpperCase()) {
      button.classList.add("active");

Tạo Bộ lọc Sản phẩm và Tìm kiếm Sử dụng HTML, CSS & Javascript

Chào mừng đến với hướng dẫn hôm nay. Trong hướng dẫn hôm nay, chúng ta sẽ học cách xây dựng bộ lọc và tìm kiếm sản phẩm. Để tạo dự án này, chúng ta cần HTML, CSS và Javascript. Vì đây là một dự án khá nâng cao, tôi sẽ không giới thiệu nó cho người mới bắt đầu sử dụng javascript. Nếu bạn là một trung cấp hoặc chuyên gia về javascript, bạn chắc chắn có thể tiếp tục và tạo ra cái này.

Hãy để chúng tôi có một cái nhìn tổng quan về dự án này thực sự là gì. Dự án bao gồm một loạt các thẻ sản phẩm. Mỗi thẻ này có tên, giá và danh mục được gán cho chúng. Phía trên các thẻ này, có một thanh tìm kiếm nơi người dùng có thể tìm kiếm một sản phẩm dựa trên tên của nó.

Bên dưới thanh tìm kiếm, có một nhóm các nút. Mỗi nút này có một tên danh mục trên đó. Khi người dùng nhấp vào bất kỳ nút nào trong số các nút này, các sản phẩm tương ứng với danh mục cụ thể đó sẽ được hiển thị.

Cấu trúc thư mục dự án:

Bây giờ trước tiên chúng ta hãy tạo cấu trúc thư mục dự án để chúng ta có thể bắt đầu viết mã. Chúng tôi bắt đầu bằng cách tạo một thư mục dự án có tên - 'Bộ lọc và Tìm kiếm Sản phẩm'. Bên trong thư mục này, chúng tôi tạo ba tệp. Đầu tiên là index.html, thứ hai là style.cssvà thứ ba là script.js. Các tệp này lần lượt là tài liệu HTML, biểu định kiểu và tệp tập lệnh.

HTML:

Chúng tôi bắt đầu với mã HTML. Trước tiên, hãy sao chép đoạn mã dưới đây và dán vào tệp HTML của bạn.

CSS:

Tiếp theo để thêm kiểu cho dự án này, chúng tôi sử dụng CSS. Bây giờ sao chép mã bên dưới và dán nó vào tệp CSS của bạn.

* {
  padding: 0;
  margin: 0;
  box-sizing: border-box;
  border: none;
  outline: none;
  font-family: "Poppins", sans-serif;
}
body {
  background-color: #f5f8ff;
}
.wrapper {
  width: 95%;
  margin: 0 auto;
}
#search-container {
  margin: 1em 0;
}
#search-container input {
  background-color: transparent;
  width: 40%;
  border-bottom: 2px solid #110f29;
  padding: 1em 0.3em;
}
#search-container input:focus {
  border-bottom-color: #6759ff;
}
#search-container button {
  padding: 1em 2em;
  margin-left: 1em;
  background-color: #6759ff;
  color: #ffffff;
  border-radius: 5px;
  margin-top: 0.5em;
}
.button-value {
  border: 2px solid #6759ff;
  padding: 1em 2.2em;
  border-radius: 3em;
  background-color: transparent;
  color: #6759ff;
  cursor: pointer;
}
.active {
  background-color: #6759ff;
  color: #ffffff;
}
#products {
  display: grid;
  grid-template-columns: auto auto auto;
  grid-column-gap: 1.5em;
  padding: 2em 0;
}
.card {
  background-color: #ffffff;
  max-width: 18em;
  margin-top: 1em;
  padding: 1em;
  border-radius: 5px;
  box-shadow: 1em 2em 2.5em rgba(1, 2, 68, 0.08);
}
.image-container {
  text-align: center;
}
img {
  max-width: 100%;
  object-fit: contain;
  height: 15em;
}
.container {
  padding-top: 1em;
  color: #110f29;
}
.container h5 {
  font-weight: 500;
}
.hide {
  display: none;
}
@media screen and (max-width: 720px) {
  img {
    max-width: 100%;
    object-fit: contain;
    height: 10em;
  }
  .card {
    max-width: 10em;
    margin-top: 1em;
  }
  #products {
    grid-template-columns: auto auto;
    grid-column-gap: 1em;
  }
}

Javascript:

Cuối cùng, chúng ta cần thêm chức năng vào bộ lọc và cũng thực hiện chức năng tìm kiếm. Để làm cho nó hoạt động, chúng tôi thêm javascript. Sao chép mã được cung cấp bên dưới và dán vào tệp javascript của bạn.

let products = {
  data: [
    {
      productName: "Regular White T-Shirt",
      category: "Topwear",
      price: "30",
      image: "white-tshirt.jpg",
    },
    {
      productName: "Beige Short Skirt",
      category: "Bottomwear",
      price: "49",
      image: "short-skirt.jpg",
    },
    {
      productName: "Sporty SmartWatch",
      category: "Watch",
      price: "99",
      image: "sporty-smartwatch.jpg",
    },
    {
      productName: "Basic Knitted Top",
      category: "Topwear",
      price: "29",
      image: "knitted-top.jpg",
    },
    {
      productName: "Black Leather Jacket",
      category: "Jacket",
      price: "129",
      image: "black-leather-jacket.jpg",
    },
    {
      productName: "Stylish Pink Trousers",
      category: "Bottomwear",
      price: "89",
      image: "pink-trousers.jpg",
    },
    {
      productName: "Brown Men's Jacket",
      category: "Jacket",
      price: "189",
      image: "brown-jacket.jpg",
    },
    {
      productName: "Comfy Gray Pants",
      category: "Bottomwear",
      price: "49",
      image: "comfy-gray-pants.jpg",
    },
  ],
};

for (let i of products.data) {
  //Create Card
  let card = document.createElement("div");
  //Card should have category and should stay hidden initially
  card.classList.add("card", i.category, "hide");
  //image div
  let imgContainer = document.createElement("div");
  imgContainer.classList.add("image-container");
  //img tag
  let image = document.createElement("img");
  image.setAttribute("src", i.image);
  imgContainer.appendChild(image);
  card.appendChild(imgContainer);
  //container
  let container = document.createElement("div");
  container.classList.add("container");
  //product name
  let name = document.createElement("h5");
  name.classList.add("product-name");
  name.innerText = i.productName.toUpperCase();
  container.appendChild(name);
  //price
  let price = document.createElement("h6");
  price.innerText = "$" + i.price;
  container.appendChild(price);

  card.appendChild(container);
  document.getElementById("products").appendChild(card);
}

//parameter passed from button (Parameter same as category)
function filterProduct(value) {
  //Button class code
  let buttons = document.querySelectorAll(".button-value");
  buttons.forEach((button) => {
    //check if value equals innerText
    if (value.toUpperCase() == button.innerText.toUpperCase()) {
      button.classList.add("active");
    } else {
      button.classList.remove("active");
    }
  });

  //select all cards
  let elements = document.querySelectorAll(".card");
  //loop through all cards
  elements.forEach((element) => {
    //display all cards on 'all' button click
    if (value == "all") {
      element.classList.remove("hide");
    } else {
      //Check if element contains category class
      if (element.classList.contains(value)) {
        //display element based on category
        element.classList.remove("hide");
      } else {
        //hide other elements
        element.classList.add("hide");
      }
    }
  });
}

//Search button click
document.getElementById("search").addEventListener("click", () => {
  //initializations
  let searchInput = document.getElementById("search-input").value;
  let elements = document.querySelectorAll(".product-name");
  let cards = document.querySelectorAll(".card");

  //loop through all elements
  elements.forEach((element, index) => {
    //check if text includes the search value
    if (element.innerText.includes(searchInput.toUpperCase())) {
      //display matching card
      cards[index].classList.remove("hide");
    } else {
      //hide others
      cards[index].classList.add("hide");
    }
  });
});

//Initially display all products
window.onload = () => {
  filterProduct("all");
};

Bộ lọc và tìm kiếm sản phẩm của bạn hiện đã sẵn sàng. Tôi hy vọng bạn thích hướng dẫn.
