Is their a science to choosing a cache sizes? I have about 500,000

What factors can i look at to determine what my cache sizes should be?
Roughly you could start with getting a count of all unique values in
all the fields you're faceting on. This would get you practically
there, though other filters get used if you're leveraging other
aspects of Solr, but the bulk of them are your facets I'm sure.
You can use Luke's first screen to get some counts, or do one facet
at a time from a fresh Solr instance and see how many filters each
one creates.
