Hi,
You should not rely on cache.size method for checking data consistency.
cache.size skips keys which is not currently loaded by read-through
behavior.

How much time does it take to iterate all results for that query ?
My test shows it take about 9 seconds to fully iterate result set on warmed

Is this OK for you?
Considering initial complex query optimization, as I already told it should
be split to 3 sub-queries to avoid OR conditions

Of course you can store result of recalculation in the temp variable if
it's needed for next recalculation.
