This search has up to 8000 records. Does this require a query cache of 8000 records? When is the query cache filled?
This answers a second question: the filter design is intended for small search sets. I'm interested in selecting maybe 1/10 of a few million records as a search limiter. Is it possible to create a similar feature that caches low-level data areas for aquery? Let's say that the if query selects 1/10 of the document space, this means that only 40% of the total memory area contains data for that 1/10. Is there a cheap way to record this data? Would it be a feature like filters which records a much lower-level data structure like disk blocks?

I thought this should be 1 insert, 4 lookups, > 4 hits, and a hitratio of 100%. Solr has a query cache too... the query cache is checked, there's a hit, and the query process is short circuited. -Yonik
