Elasticsearch java api reference

Hi,

Where do I find a 'real' elasticsearch java api reference? Not just some
examples of a few classes like here:
http://www.elasticsearch.org/guide/reference/java-api/

Thanks in advance

Um, is there really no api reference?

No, looks like there isnt (and believe me, I searched for it ;-)) Until
several versions ago there were at least javadocs available for download,
but this disappeared somehow. Solution is the classical do it yourself
approach: download source and generate javadoc. What helped me in the past
was: 1. searching this mailing list and 2. read the the source code,
usually you can figure out pretty good what is going on when looking at how
rest requests are transformed into java api calls or what is covered in the
test cases.

There is not much in the way of Java API reference, but the Java API
closely mirrors the JSON API. In practice, I usually figure out what I want
to do in the JSON API, and then find the corresponding Java API helper
methods in the Elasticsearch source code. It’s not ideal, but it also isn’t
too time consuming.

Would Elasticsearch be open to accepting documentation patches for the
query API that included examples in Java?

The JSON API does indeed closely resemble the Java API. The elastic.js
library takes advantage of that fact and provides
comprehensive documentation of the query DSL.

Heya,

We pushed already some recent updates in the Java documentation.
We described Queries [1] , Filters [2] and Facets [3] in Java.

Can you describe what you would like to have in addition of that?

Hi David,

Wow, those are really great improvements. I noticed someone was committing new Java documentation, but I hadn’t realized how far along it had come. Thanks, it looks really great. I was imagining that in the query-dsl section of the documentation (Elasticsearch Platform — Find real-time answers at scale | Elastic) each JSON example could have a corresponding Java example, either beneath it or linked from it. But I think the way things are set up now could work too, if I get in the habit of looking at the java-api documentation rather than just skipping sight to the Elasticsearch source.

Those updates are for sure an improvement, thanks once again! What comes to
my mind what would be still interesting:. 1. ready to use/download javadocs
(with maybe a little bit more docs inside) :wink: 2. maybe a short tutorial
like guide how to make use of metadata (what is included, how to resolving
aliases, getting mapping information, etc.). I believe new users would
benefit, this is not really straight forward or at least it took me quite
some time to puzzle it out.

Thanks!
Andrej

+1 for all admin commands in Java. I add it to my ToDo list.

For Javadocs, you can attach source code to your project.
https://oss.sonatype.org/content/repositories/releases/org/elasticsearch/elasticsearch/0.20.5/

It's not direct Javadoc for sure but should help at least.
