In my previous post I tried to provide highlights on Elastic App Search, which provides Search as a Service. As mentioned in the post, Elastic provides client implementations for a number of languages; however there are no implementations for Java or Kotlin. So I decided to implement my own.

I was particularly excited to do this, since I’ve been using Elastic Stack (Elasticsearch mostly) for years and App Search was in my radar for a while. This was a great opportunity for me to deep dive in App Search and contribute to the ecosystem. As the name suggests, I selected Kotlin as the implementation language. As you might already know, Kotlin is my favorite programmng language and it’s on JVM.

Apart from those it was the first time I managed to deploy a library to public Maven repositories and streamline the process via GitHub Actions.

In the following sections I will try to go over some details on app-search-kotlin implementation.

Disclaimer

app-search-kotlin is a client implementation for App Search that I developed as a side project and should not be treated as a production quality and included in the projects accordingly.

Location

Source code is located in Github. app-search-kotlin JAR is available at search.maven.org .

Compatibility

app-search-kotlin has been developed using version 7.8.1 of Elastic Stack (Elasticsearch and Elastic App Search). I did not test against other 7.x.y versions but theoretically it should work.

Library is developed with Kotlin 1.3 and Java 11 and not tested for other versions. Similar to the Elastic Stack version, it should work with no or minimal changes but a rebuild might be necessary.
