Subject Can NOT be used with a single Term?
Date Thu, 16 May 2002 15:22:57 GMT
According the Jguru FAQ


Is it possible to find all documents in the index that do not contain a
certain term? In other words, is it possible to make a query such as 'NOT
<term>'? 


No, it is not possible to do that with Lucene. Lucene could be modified to
do that, but such queries would be very slow.
