Hi,

I want to implement some pseudo-relevance feedback (something like: Relevance Based Language Model - Lavrenko, Croft, SIGIR 2001) mechanism in the Elasticsearch. I already have an implementation in Lucene, tested with TREC data ([https://github.com/dwaipayanroy/Relevance-Model](https://github.com/dwaipayanroy/Relevance-Model)). Is there a way to do that in the Elasticsearch as well?

I want to incorporate the relevance feedback inside a running system which is build with Elasticsearch.

Any help will be appreciated.

Best,  
Dwaipayan.
