Either I am overlooking something (please open my eyes!) or a very basic feature is missing in the megafilter within tags:
The "AND" function for filtering.
Currently the filter seems to offer "OR" only.
Example:
If on a car presentation website I select tag "VW" and tag "red"
I don't get all red Volkswagen, but all red cars (BMW, Chevrolet, Buick, Toyota... you name it) AND all Volkswagen - blue, yellow, pink and .... even red ... :-)
The AND function is working, however, across various filter items - i.e. if I select a certain author, it reduces the selection within the tags. For my particular case a work around would be to have the base field "language" as a selection criterion. Unfortunately that is missing - leaving me only with the option to "TAG" the language (which produces the weird results described above).
Thanks
