RE: Problems with prohibited BooleanQueries

Lucene does not implement a standalone "NOT" query. (Probably BooleanQuery should throw an exception if all clauses are prohibited clauses.) Negation is only implemented with respect to other non-negated clauses. So you cannot directly model your query tree as a Lucene query tree. NOT nodes mu

Brackets in query syntax?

Are brackets, [ and ], legal in a query? If so, do they have some special meaning? If not, are there other "illegal" characters as well? Parsing the query syntax, "[]", causes the following error: Lexical error at line 1, column 3. Encountered: after : "[]" org.apache.lucene.queryParser.Toke

Re: Tutorial

I had the same problem and have started to write down all my own notes and experiences. I was hoping this could be put into a manual/tutorial in the future. I was going to wait until it was a bit more robust, but let's see if we can create some coordination. Is anyone else out there creating a

Problems with prohibited BooleanQueries

Hello, I have some trouble understanding the semantics of the BooleanQuery with regards to prohibited clause. the method I am using is this: public final void add(Query query, boolean required, boolean prohibited) in the class BooleanQuery. I am not using the QueryParser, but instead I buil

RE: Tutorial

*This message was transferred with a trial version of CommuniGate(tm) Pro* Haven't seen any really simple tutorials since I've been using it. The best place to start though is the FAQ at http://www.lucene.com/cgi-bin/faq/faqmanager.cgi . I read completely through it several times and was finally a

RE: Querying an exact string match ?

This should work. You should be able to find an un-tokenized field containing spaces with a TermQuery. Nothing should ever tokenize the string. Can you please supply a simple, self-contained example showing that this does not work? Thanks, Doug > -Original Message- > From: Winton Dav

Determining hit field

Hi, (Apologies if this shows up twice). If I do a search such as "field1:jim OR field2:bob" is there any way to determine for each document that was a hit, which field caused the hit? Or rather, since they both might, is there any easy way to find out which fields definitely didn't cause a hit

Querying an exact string match ?

Hi, I have a field which I need to match exactly -- Ideally it shouldn't even be tokenized, but I can't find a way to do that -- adding a field that is indexed but not tokenized, doesn't seem to work -- or at least a Term Query doesn't work. eg the field is "x y z" -- and I do a phrase qu

Re: Fw: Exception when search with accents.

Its a problem with the query parser, but this is not the correct fix. I think this fix just masks the problem. > I think it's the bug of QueryParser.jj file because there the term is > definied as character string that begins with any English character. > > Modify a line in the QueryParser.jj: >
