Custom Cache cleared after a commit?
I know the queryResultCache and stuff live only so long as a commit happens
but I'm wondering if the custom caches are like this as well? I'd actually
rather have a custom cache which is not cleared at all. I want to give the
elements of this Cache a 6 hour TTL (or some time frame) but I never want it
to clear on a commit. Is this possible using SolrCache?

Sorry for my ignorance, but do you have any lead in the code on where to look
for this? Also, I'd still need a way of finding out how long its been in
the cache because I don't want it to regenerate every time. I'd want it to
regenerate only if its been in the cache for less then 6 hours (or some time
frame which I deem to be good). Thanks

You can specify a regenerator for your cache that examines items in
the old cache and pre-populates the new cache when a commit happens.

That's not currently possible.
The nature of Solr's caches are that they are completely transparent -
it doesn't matter if a cache is used or not, the response should
always be the same. This is analogous to caching the fact that 2*2 =
4. Put another way, Solr's caches are only for increasing request
throughput, and should not affect what response a client receives.
