This package uses synonyms defined by WordNet to build a
    Lucene index storing them, which in turn can be used for query expansion.
    You normally run {@link org.apache.lucene.wordnet.Syns2Index} once to build the query index/"database", and then call
    {@link org.apache.lucene.wordnet.SynExpand#expand SynExpand.expand(...)} to expand a query.
    
	
 Instructions 
	
	    -  Download the WordNet prolog database , gunzip, untar etc.
	
-  Invoke Syn2Index as appropriate to build a synonym index.
	    It'll take 2 arguments, the path to wn_s.pl from that WordNet downlaod, and the index name.
   
	 
-  Update your UI so that as appropriate you call SynExpand.expand(...) to expand user queries with synonyms.
