WordNet Lucene.Net Synonyms Integration

This package uses synonyms defined by WordNet to build a Lucene.Net index storing them, which in turn can be used for query expansion. You normally run {@link WordNet.Net.Syns2Index} once to build the query index/"database", and then call {@link WordNet.Net.SynExpand#Expand SynExpand.Expand(...)} to expand a query.

### Instructions

1. Download the WordNet prolog database , gunzip, untar etc.
2. Invoke Syn2Index as appropriate to build a synonym index. It'll take 2 arguments, the path to wn_s.pl from that WordNet download, and the index name.
3. Update your UI so that as appropriate you call SynExpand.Expand(...) to expand user queries with synonyms.
