thanks, i saw the queryparser documentation and works fine.

I really don't know how use JavaCC, but may be for someone is easy,
someone can help me?
thank you.

This is a bit more complicated.

We have had this discussion a while ago about having a NEAR operator. The
queryParser.jj of how to do this in the developer mailling list.

The problem is that the solution is not generic. That is what if the term is
a wildcard or a more complicated sub query (a query in parentheses).

For example
(a AND b) w/ c

This type of query is not supported by the Lucene Slop factor. That's why
it's not support in Lucene as part of the general QueryParser.

If you are willing to live with these limitations, the queryParser.jj with
the NEAR operator should work.

the developer list sent my question to the user list!
Are you telling me that i can write 'NEAR' instead of '~'?
I have the rc4, do i need to update to rc5?
What about the case insensitive operator? is ther any way to do that?
bye

It may be easier to have your User Interface convert user-entered 'and'
'or', etc... into the proper 'AND' 'OR' etc... just prior to calling the
query parser.
