Subject Re: Garbled facets even in a zero hit search
Date Thu, 09 Sep 2010 13:10:29 GMT
That looks...er...unfortunate. The very first thing I'd do is check your
index
and see if there are such weird values in your facet fields. My guess is
that SOLR is working fine, but you somehow have garbage values
in your index, but that's only a guess. I'd try that before trying to
debug, GIGO.

Which wouldn't answer the question of how the garbage got in there
in the first place, posting your field type definition for your
faceted fields would help with that question.

Best
