Negative bias filtering not working. #28

According to document the negative bias should filter out all properties except values which are passed as part of query. But when giving a negative bias it is returning empty result set.

then there are no recommended items with all of the property values you specified. This is why you should use boosts, since they will favor items with some of the values you specify but return results even if there are none

BTW, please use the google group for questions.
