Subject Re: Lucene and LSA

Lucene has term vector capability, which facilitates LSA types of  
things.  For a field you can get back all the terms in it, their  
frequency, and their positions.  Enabling this requires setting the  
flag appropriately on the field during indexing.

Hope that helps.
