I want to implement a classic query expansion (Rocchio method for example) for ElasticSearch.
Basically what I need to do is to retrieve the term vectors of the top N relevant documents given an original query, extract a list of terms based on some criteria, and finally get enriched document results with a expanded query. Surely I can do that by searching twice, but is there any better solution that I can do it *IN* the ElasticSearch? Do you have any suggestions about where and how I can implement it?
