All: Hive blog, Peakd, Ecency, even dbuzz, etc. I posted abt it sometime ago on dbuzz. There are times it just happens.

Maybe when it happens again I'll let you know. Or maybe someone should check on it regularly? I dunno.

Ok, it is basically all integrations. Perhaps your search was recently performed while we were doing reindexing.
Then let’s try what content you wanted to find and what keywords used? From there we can see fault and try to fix it. We recently reindexed entire search, if improvements needed we will apply and reindex again

I just used random words when I realized there was an error. However lately search has been working so I dunno when the next error will happen.

Makes sense, It was likely during re-indexing which we did recently after one of our cluster server crashed.
