WordNet synonyms overhead

[Harald Näger <ha...@gmx.de>]

Hi,

I am especially interessted in the WordNet synonym expansion that was 
discussed in the "Lucene in Action" book. Is there anyone here on the list 
who has experience with this approach?

I'm curious about how much the synonym expansion will increase the size of an 
index. Are there any reliable figures of real-life applications?

Kind regards,
Harald

Query expansion is better than index expansion. Faster use, smaller 
index, less noise when you search.
