Exactly.

We're doing too much work processing search results. We need to streamline this
process to avoid repeated handling, unnecessary lookups, etc. 

Besides getting performance improvements, we'll also gain some future-proofing
by abstracting away from MARC based search result processing.

I'd argue that we should be retrieving the bare minimum from Zebra and then
doing the minimal amount of transforming possible. Failing that, if we have to
fetch whole MARC records from Zebra, let's set up an optimized pipeline.

I reckon that there's no *technical* reason that search shouldn't be fast in
Koha.
