[ckan-dev] ckan text search problem

Mon Dec 23 12:01:57 UTC 2013

Hello

It appears you are using the multilingual plugin.  The multilingual
plugin has to be on when you reindex too, if not it will not work.

Apart from that, it is hard to tell if its due to not being indexed
correctly or if the querying is off.  My guess is that this if the
default language of you instance is not English there could be
troubles, but that is just a a guess.  Also there are sometimes issues
with certain stopwords causing the search to go awry.

Does the search always return no results or it is only certain words
that it seems to fail at?
