enablePositionIncrements="true" causes searches to fail when they are parse as
phrase queries
---------------------------------------------------------------------------------------------
Key: SOLR-1852
URL: https://issues.apache.org/jira/browse/SOLR-1852
Project: Solr
Issue Type: Bug
Affects Versions: 1.4
Reporter: Peter Wolanin
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. Our default handler is dismax, but this
also fails with the standard handler. So I'm wondering if this is a
known issue, or am I missing something subtle in the analysis chain?
Solr is 1.4.0 that I built.
test string: Identi.ca
queries that fail: IdentiCa, Identi.ca, Identi-ca
query that matches: Identi ca
schema in use is:

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 WordDelimiterFactor
