This bug exists on other database types also afaik. Any chance of a holistic fix across all DB types?

We could switch from MATCH to LIKE in general. All three DBs systems currently supported would support LIKE, with the only (manageable) pinpoint being them not uniform with case sensitivity. We might want to have some way to make whole world search available though. I think it might be best to implement some sort of query language that enables searches as alias:"CITY" message:"FIRE" -message:"Test"
