Wildcard searching and highlighting with Solr 1.4

Question

I\'ve got a pretty much vanilla install of SOLR 1.4 apart from a few small config and schema changes.

Answer 1

Or you can grab the latest nightly build and use edismax (ExtendedDismaxQParser).

It handles both trailing and leading wildcards.

Answer 2

From what I know you can't use wildcards with the dismax handler, see http://wiki.apache.org/solr/DisMaxRequestHandler#q.

To simulate wildcard searching I used EdgeNGrams following some of the instructions here: http://www.lucidimagination.com/blog/2009/09/08/auto-suggest-from-popular-queries-using-edgengrams/. Actually I really only added the edgytext fieldtype to schema.xml and changed the fieldtype of the field I wanted to search.

Hope this helps!
