Hi, I had a filter type that was interacting poorly with the Solr filterCache--identical filters were causing _2_ filterCache insertions per query.
The field is for a url's domain name, and for some reason WordDelimiterFilter was being uses with generateParts=catenateWords=1. The filer query looked something like "domain:org.python.www", which produced the following Query: MultiPhraseQuery(domain:"org python (www orgpythonwww)")' Now, there really is no need for the part catenation, so I turned it off. The parsed query is now: PhraseQuery(domain:"org python www")' and the filterCache is working as expected. I'd suspect a bug in MultiPhraseQuery.equals(), but glancing at it, it looks fine. Ideas? -Mike
