Such a parser would differ in the behavior of the default parser in the following points: - Default AND rather than OR. - Treat a-b as "a-b" rather that a -b. - Perhaps disallow ~. I guess I could write my own QueryParser, just wanted to be sure it hasn't been done already, especially as it seems to be something rather basic. Any suggestions? By the way, I was honestly surprised by the compactness of the indices Lucene generates, as well its performance. I had always thought there was a trade-off between good design and speed... great work! -- Eric Jain -- To unsubscribe, e-mail: For additional commands, e-mail:
