Tim, That's because Lucene defaults to "OR" operator unless you override that explicitly. Probably, you can try giving your keywords in quotes or with "AND" operator and check.

I have a search text box in my app, but the more words I add into the search box, the more documents it finds. I want it to work the opposite way around, so fewer are found. In other words I want to search on "word1 AND word2 AND word3" rather than "word1 OR word2 OR word3". I'm sure it's trivial, pointer welcome. Tim
