I haven't tried it but I guess you need to change the getXXXQuery() methods so
they return a BooleanQuery. For example,
You might run into problems with having too many Fields by treating each
record as a Document and each column as a Field in that Document. An
alternative would be to index each cell of the table as a Document and

I am attempting to query a field in my index for all unique values. I am
using the following call to get all the unique values of the field:
TermEnum enumerator = reader.terms(new Term(field, ));
where read is an IndexReader and 'field' is the field name.
However, I would like further limit
I would think the following strings passed to the QueryParser should
yield the same results:
#1: +telescope AND !operate
#2: (+telescope) AND (!operate)
However the first string seems to give the correct results while the
second gives zero hits. Am I misunderstanding something or is there
I gather from reading the documentation that the scores for each document hit are
computed at query time. I have an application that, due to the complexity of the
function, cannot compute scores at query time. Would it be possible for me to store
the documents in pre-sorted order in the
