> Symptom: searching for a string like a domain name containing a '.', the Solr 1.4 analyzer
tells me that I will get a match, but when I enter the search either in the client or directly
in Solr, the search fails. 
> test string:  Identi.ca
> queries that fail:  IdentiCa, Identi.ca, Identi-ca
> query that matches: Identi ca
> schema in use is:

> Whether or not the bug appears is determined by the surrounding text:
> "would be great to have support for Identi.ca on the follow block"
> fails to match "Identi.ca", but putting the content on its own or in another sentence:
> "Support Identi.ca"
> the search matches.  Testing suggests the word "for" is the problem, and it looks like
the bug occurs when a stop word preceeds a word that is split up using the word delimiter
filter.
> Setting enablePositionIncrements="false" in the stop filter and reindexing causes the
searches to match.
> According to Mark Miller in #solr, this bug appears to be fixed already in Solr trunk,
either due to the upgraded lucene or changes to the WordDelimiterFactory
