Hi all, I want to directly access low level ElasticSearch (or in other words Lucene) index from a plugin, so that I can say iterate through an inverted index of a keyword in the plugin. I know from ElasticSearch source code one can access the ContextIndexSearcher instance (which has an IndexReader member) from SearchService to directly access the inverted index. However, I could not figure out how to get the handle to either the ContextIndexSearcher instance or the SearchService instance from a plugin. Any suggestion here will be highly appreciated!

I think you can try to inject the SearchService in the plugin? Have a look at this. We inject here another service.
