Api Key Authorization
You can use logical operator for tag filtering. If you add "-" operator in front of a tag, it implies a NEGATE; if you add "^" operator to the end of a tag, it implies an OR.
For example, if you like to see all the devices tagged as "house", and tagged as either "kitchen", "bathroom", or "bedroom" but not tagged as "mansion" you should set a tag filter as:
?tags=house, kitchen^, bathroom^, bedroom^, -mansion
