Wildcard searches within phrases to use proximity
Is there a trick that I can use to use a wildcard operator within a phrase
in order to use proximity? What I'm after is something like this:
"bal* gui"~10
So I would get results with "baltimore" within 10 of "gui", and also
"balance" within 10 of "gui".
Thanks,
-Jay

Thanks Ahmet, I've marked the issue for 1.5 so we do not forget about it.
I'll take a look at the patch soon.

Hi Shalin,
I opened an issue (SOLR-1604) and attached a patch as well as a maven project to enable this feature without applying the patch. I couldn't consume ComplexPhraseQueryParser from lucene-misc-2.9.1.jar. Because there is a fixed bug but it is not included in lucene release. LUCENE-1486 says guidance needed from the Solr team about preferred course of action.
I will add more test cases to the patch in the future.
Thanks.

You can do it with the complexphrasequery parser in lucerne contrib (I
think that's the name). You have to plug it in to solr though -
someone has already donethis bit I'm not sure if it was controbbed back.

What you are looking for is ComplexPhraseQueryParser [1] and implemented in Lucene 2.9.0. I am using it with solr 1.4. I have faced some highlighting problems but it retrieves documents perfectly. It uses SpanQuery family. If you need i can share solr integration related java code.
It supports "bal* gui"~10 as well as "(baltimore balance) gui"~10 also
"[bal TO bak] gui"~10. Ranges, OR and wildcard inside proximity (phrases).
