Re: Questions about Lucene usage recommendations

You said you have 1000 fields...when performing search do you search in all 1000 fields? That could definitely be a major performance hit, as it translates to a BooleanQuery with 1000 TermQueries inside Maybe it make sense to concat data from fields that you search in fewer fields (preferably ONE)
