Description

In Lucene and Solr, query words that are prefix or wildcard or fuzzy do not go through analyzer processing. This is for well known understood reasons. However, for my data for a field I might want certain processing to occur. Lowercasing has already been identified in SOLR-219. Another which I address in the attached patch file is the ability to remove characters that meet a supplied regular expression. I've implemented this as part of SolrQueryParser but there should probably be a more thorough plan such as an analyzer chain expressly for the purpose of being applied to prefix, wildcard, and fuzzy queries.
