Hi all,
We're using Solr to search on a Shop index and a Product index. Currently a

I should have explained that the queryMode parameter is for our own custom

All the filter parameters (30 or so) of the query time and index time are

Hi,
We use solr and lucene fieldcache like this

which is initialized at first use and will stay in memory for fast retrieval
of field values based on DocID
The problem is after an index/commit
There is no simple answer.
All I can say is you don't usually want to use an Xmx that's more than
you actually have available RAM, and _can't_ use more than you have
available ram+swap, and the Java error seems to be suggesting you are
using more than is available in ram+swap. That may not be

Could be related to your crazy high MaxPermSize like Marcus said.

Hi Gaurav, not sure what your use case is (and if no sorting at all is ever

There's no great way to do that.

First guess (and it really is just a guess) would be Java garbage

AFAIK it shouldn't affect search time significantly as Solr caches it
