Wildcard search in Solr

Question

I am having a problem doing wildcard searches in lucene syntax using the edismax handler. I have Solr 4.0 nightly build from the trunk.

A general search like \'comp

Answer 1

With edismax, leading wildcards are no problem. I just retested it.

Wildcards in middle of term are no problem either.

Looks like there is something else wrong. Are you sure you are using edismax?

Answer 2

Leading wildcard won't work unless you activate the reverse string filter. To use it in Solr, add a ReversedWildcardFilterFactory to the analyzer of the field that you want to search with a leading wildcard.

As for your other queries that return 0 result, try using luke to see how your terms are being analyzed (stored in the index). Don't forget to take into account the effect of stemming, if you are using it.
