fix(rpc): improve type=search performance

This patch brings in the use of .with_entities on our RPC search query. This primarily fixes performance issues we were seeing with large queries.

That being said, we do see a bit of a slowdown on large record count rpc queries, but it's quite negligible at this point.

We still do aim to perform better than the older PHP implementation, so this is not a finishing patch by any means.
