At the risk of committing a gaffe, I recently did a blog post about
queries and "multi term aware" capabilities newly added to Solr. The
short form is that the recurring problem of wildcard queries (and some
other types, e.g. range) not automatically lower-casing (or accent
folding or a few others) has changed as of Solr 3.6 (i.e. 3x ) and
Solr 4.0. The app no longer has to apply certain transformations to
get matches to occur.

Here's the blog post:

Here's the Wiki page for Solr:
