Yes, after posting that response, I read some more and came to the same
conclusion... there seems to be some interest on the dev list in
building a capability to specify an analysis chain for use with wildcard
and related queries, but it doesn't exist now.

I'm not familiar with the CharFilters, I'll look into those now.
Is the solr.LowerCaseFilterFactory not handling wildcards the expected
result or is this a bug?

I wonder whether CharFilters are applied to wildcard terms? I suspect they
might be. If that's the case, you could use the MappingCharFilter to
perform lowercasing (and strip diacritics too if you want that)

So simply lower casing the works but can get complex. The query that I'm
executing may have things like ranges which require some words to be upper
case (i.e. TO). I think this would be much better solved on Solrs end, is
there a JIRA about this?

Wildcard queries aren't analyzed, I think? I'm not completely sure what
the best workaround is here: perhaps simply lowercasing the query terms
yourself in the application. Also - I hope someone more knowledgeable will
say that the new HighlightQuery in trunk doesn't have this restriction, but
I'm not sure about that.

I have a field defined as
<field name="Person_Name" type="text" stored="true" indexed="true" />
when I execute a go to the following url I get results
http://localhost:8983/solr/select?defType=lucene&q=Person_Name:kris*
but if I do
http://localhost:8983/solr/select?defType=lucene&q=Person_Name:Kris*
I get nothing. I thought the LowerCaseFilterFactory would have handled
lowercasing both the query and what is being indexed, am I missing
something?
