Sure, your problem is probably that the query goes through an analyzer and its associated tokenizer. Probably something like StandardAnalyzer which "massages" the input and strips out most non-alphabetic characters,.... except some. It tries to be smart about URLs, e-mail addresses, etc.
If you're new, I recommend you use WhitespaceAnalyzer until you get familiar with what analyzers do for you. Be aware that WhitespaceAnalyzer does NOT automatically lower-case your input, so "Which" won't match "which". It's easy enough to make your own analyzer by subclassing of the standard ones. The book "Lucene in Action " is valuable for this, although you should be aware that it was written to the 1.4 codebase, so there are a few differences. It is important that the analyzer you use at *index* time is compatible with the one you use at *query* time. Until you're more familiar with this, I simply recommend you use the *same* analyzer at index time that you use at search time. That'll give you more intuitive results. You'll want to refine the use of analyzers later... I also recommend that you get a copy of luke (google lucene luke). It will allow you to examine your index, parse queries through the GUI, examine the effects of different analyzers on input etc. It's a great tool and one that'll make your life much easier.

Hi there, this is my very first post at this forum... please be considerate :) Well, i have a problem when sending a query such as: +description:< Once the query is parsed, it returns me the empty String, which means the String "<" that i want to search for on the field description is ignored. If i use normal words then it is taken. Do you know why this could be? Thanks. -- View this message in context: http://www.nabble.com/Problem-with-lucene.-tf3137405.html#a8694565 Sent from the Lucene - Java Users mailing list archive at Nabble.com. --------------------------------------------------------------------- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
