----------------------------------------

This looks like a Won't Fix?

> 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?
