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*
<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*
<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?
