Im having perfomance issues with facet on multivalued field with an index over 20Million documents.
And when doing faceting search on multivalued field the QTIME is unacceptable for my application because it can take up to 6000ms. Ive put the facet.method to enum! Which increased my performance to the time i just mentionned! Its still not acceptable. Is there any suggestions ?

I am guessing at times people are lazy about schema definition. But, I think with lucene 4 stats we can detect if a field is actually single valued... Something like terms.size == terms.doccount == terms.sumdocfreq. I have to think about it a bit, maybe its even simpler than this? Anyway, this couple be used instead of actual schema def to just build a fieldcache instead of uninverted field I think... Should be a simple opto but maybe potent...
