Within Search

[none none <ko...@lycos.com>]

hi,
i asked some help about this feature some time ago, but no answer.
What do i need to do is the WithinPhraseSearch. An example can be:

search for:  "car w/10 rent".

This mean, look for documents that contains 'car' and within 10 words 'rent'. So, what i think i need is:

1.Change the QueryParser.jj to reconize the operator "w/xx" as the within operator.

2.The QueryParser should return a PhraseQuery with a "slop" factor equals to '10' for the example above. Should also ignore "w/xx" if xx is not numeric.

An other question: what should i do if i want the query operator (AND,OR,NOT,etc) to be case insensitive? what should i change inside the QueryParser.jj ? 

PLEASE HELP, because i really don't know how to use the "JavaCC" utility.

Thanks,
bye.

Hello,

I'm sending this to lucene-user list, as that seems more appropriate.
I haven't used Lucene's slop feature, but it looks like both
QueryParser and PhraseQuery have support for slop.  I am not sure what
the syntax for it is, but if nothign else you should be able to call
setSlop(int) method on an instance of PhraseQuery.

Oh, it looks like you missed it in the Query Parser Syntax document:
http://jakarta.apache.org/lucene/docs/queryparsersyntax.html
