Hi, How can I dynamically plug a custom query in ES? What I did for the moment, is to modify the IndecesQueryRegistry and there I added the following line: addQueryParser(queryParsers, new AATermQueryParser()); where AATermQueryParser is the parser for my custom query syntax. I'm working with the ES source code. But I'm interested in doing this dynamically. So, any suggestions? Thnx in advance, Alex ---

Write a plugin that does that. You can write a class that gest injected with IndicesQueriesRegistry, and adds teh relevant parsers you want, and write a module that registers your class.

Thnx for the tip. I didnt used the IndicesQueriesRegistry. Instead I used the IndexQueryParserModule. @Override public void processModule(Module module) { ``` if (module instanceof IndexQueryParserModule) { System.out.println("---------> Registering AATermQueryParser"); ((IndexQueryParserModule) module).addQueryParser("aaterm", ``` AATermQueryParser.class); ``` } ``` } Tnx, Alex On Mon, Nov 28, 2011 at 12:33 PM, Shay Banon [kimchy@gmail.com](mailto:kimchy@gmail.com) wrote: > Write a plugin that does that.

That would work as well 🙂 On Mon, Nov 28, 2011 at 6:16 PM, Sisu Alexandru [sisu.eugen@gmail.com](mailto:sisu.eugen@gmail.com)wrote: > Thnx for the tip.
