com.flaptor.indextank.query.TermQuery
Query that searches for a specific term in a specific field. The term passed to the constructor does not suffer any modifications, no case conversions, no tokenization. So great care has to be taken to be sure the term passed is consistent with the tokenization made at index time. @author spike
