@matej_suchanek I can't see the error on wikidata since I don't have enough filters, nor I can replicate on beta cluster.

True, so we need additional checks?

I would just disable the search for global filters.

@matej_suchanek Mmmmm I like it, would solve many, many problems. I'll try and do it later, or feel free to edit my patch if you want to do it yourself :-)

I want to use this opportunity to complain that a clear, step-by-step process for replicating the design of WMF's wiki farm is not out there and no matter how much I try to replicate it I cannot do it closely enough.

This bug did *not* occur on my local wiki farm, hence my approval of the original patch. Had I been able to create a wiki farm that is exactly like WMF, then I would have caught it when I was testing the search of global filters on my local wiki farm.

@Huji Yeah, you're right. Anyway, removing search from global filters is probably better, and if needed we may add it again in the future. The only note is, I'm not totally sure I removed it in the right way. I'd like a review from someone more experienced than me with global filters for this patch.
