Code location pointer

Elastic Stack Elasticsearch
1

Hello,

I was wondering if someone here in the community could help me with some code location pointers.

I am working on a project, and as part of the project I am looking at the Elasticsearch source code. I am interested in finding the java files implementing certain functions of Elasticsearch. For example I am looking for the implementation of Query DSL. I will be happy with a directory location or file location. No need to go into details on the specific files (you can if you'd like, that would help too), I can do that myself, but a location to start looking into will certainly save me a lot of time. Obviously if you have pointers to other features I welcome those too.

I appreciate the help in advance!

There are many parts involved in processing query by elasticsearch.
If we take with a simple term query, you can start with TermQueryBuilder, which is a builder object for a query that allows to decode a query from json and translate it to a corresponding Lucene query with the method doToQuery. Then the Lucene library will execute the query.
