--- Comment #27 from David Cook <dcook at prosentient.com.au> ---
I have been thinking that maybe we should modularize search more so that it
would make it easier to customize behaviour, unit test, and swap different
backends in/out, but... I think one of the biggest struggles we face is that
Koha doesn't really have a search query language. 

We have something like CCL, but it's not CCL, and our compensating for that
fact leads to problems. And without a real query language, we don't have a real
query parser, and without a real query parser, it's hard to safely and
programmatically alter the queries. 

But... I don't really have a solution in mind either. Sometimes, I hope that
we'll just get rid of Zebra, and then we can just focus on Elasticsearch, and
maybe change our search query syntax to be safer, easier to parse, and easier
to integrate with Elasticsearch. I think it would be a breaking change away
from the Zebra CCL-like search syntax we've used... but that would probably be
a good thing.
