The features table (http://www.relevanssi.com/features/) for relevanssi, says that free version supports category search. I have enabled category indexing in relevanssi config, in a hope that when I type "Milk" in the search box, relevanssi will return all posts assigned to "Milk" category. However, the search returns an empty set. Am I doing something wrong? I have an impression that this feature worked prior to 3.0 but I may be mistaken.
I'd appreciate a hint.
