I cannot figure out how to search for itms matching to multiple words on the this Tiki site. For example, I'd like to search for items that contain both words "forum" and "email". Just entering the 2 words in the search box gives all items that contain EITHER of these words - which is way too many. Using "forum+email" made no difference. I looked the the documentation for fulltext search mode and tried '+form +email' but that led to an error.
On my own Tiki installation, I get the proper behavior only using simple search mode, and have the same issues with fulltext mode.
I am sure I am missing something obvious. Can someone please point out what I am missing.
