query formulation
Hello,
I'm wondering if there is a way to configure the query in lucene to use
the logical operation ?
In fact, I would like to force retrieval of documents which contain
obligatory a given keyword or do not contain an other one. I can do that
by a preprocessing (filter the documents which contain the keyword) but
I would like to that in the query formulation.
Many thanks

Hmmmm, have you seen this page?
http://lucene.apache.org/java/3_0_3/queryparsersyntax.html
<http://lucene.apache.org/java/3_0_3/queryparsersyntax.html>If that doesn't
help, perhaps you can explain what it is that you're trying to do that the
syntax
is inadequate for.
Do note that Lucene query syntax is better thought of with the +/-/ / syntax
(this last is a blank
operator standing for "should". It's not true boolean logic.
Best
