[jira] Updated: (SOLR-2386) Filter Query Cache Improvement
[ https://issues.apache.org/jira/browse/SOLR-2386?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Frederik Kraus updated SOLR-2386:
---------------------------------
Description:
Currently logically identical filter queries are not reduced to one query, but processed and cached individually.
In terms of cache "keys" the following two, logically identical queries, each have a different key:
fq=id:12345 OR id:54321
vs
fq=id:54321 OR id:12345
Internally both queries should be stored and requested by/from the cache as fq=id:(12345 OR 54321) i.e. the clauses in BooleanQuery should be sorted.
Not sure where this would fit best. Lucene/BooleanQuery looks like a natural place to do this sort, but might be more a solr optimization?
