    Description

      Based on our discoveries, we will be implementing a BM25/Rocchio expansion model.  Garrick has a preliminary implementation using Lucene 6.6, see NDS-829.

      This task is to implement Rocchio expansion using the ElasticSearch plugin framework prototyped in NDS-840.

      Note:

      • As a first step, our plugin¬†just does expansion: given an original query, return the expanded query
      • We need to be able to demonstrate support for expansion over different elasticsearch indexes (e..g, BioCADDIE, PubMed, Wikipedia)
