wildcards searches and hyphens

[liowalter]

There is a problem with wildcard searches which contains also hyphens :

• grand-père
• gra*d-père -> no results
• gra?d-père -> no results

This is the same with vufind core

• grand-père
• gra*nd-père

The query is correctly sent to solr, but solr cannot process it correctly

• http://localhost:8984/solr/green/select?q=title:gra*d-pere -> no result (standard query parser)
• http://localhost:8984/solr/green/select?defType=edismax&q=gra*d-p%C3%A8re&qf=title -> no result (edismax)

Currently, during indexing grand-père yields 3 tokens : "grandpere", "grand", "pere".

One possible solution might be to use preserveOriginal=1 in the WDGF filter.

Or catenateWords=1 at query time as well.

But this is still unclear to me why this happens.
