Alright, I've talked to my wife and my neighbors about what they expect from clicking multiple tabs, and almost everyone expects each click to reduce the amount of pictures in the list. So, that means AND behaviour. However, nobody (even those who thought that clicking tags should increase the amount of photos, ie OR behaviour) wants to use the keyboard for advanced searches.
I've discovered that there are two scenarios that people would use tags to navigate their photo collection: 1) Searching for a particular photo. In this scenario, the user has a particular photo in mind, and wants to find it. Each click should reduce the number of photos displayed, narrowing down the search to just a few photos so that the desired photo can be found easily. In this scenario, only the AND operator is necessary. 2) Searching for ideas. In this scenario, the user knows what he wants in general, but has no particular photo in mind. Examples of this are websites, invitations, email, etc. In this scenario, the first tag should narrow down the search, and the rest would either broaden or narrow down the search. So, both OR and AND operators are necessary. I propose a 'switch' that has two modes: BROADEN and NARROW. The button should be clearly visible near the tags, and both words should be displayed at all times. Also, it should be clear in what mode the switch is. When the switch is in BROADEN mode, a click on a tag will expand the number of photos shown, and in NARROW mode, a click will reduce the number of photos shown. These terms are much easier for mortals to comprehend than OR and AND. Also, the user knows exactly what behaviour to expect while operating it. The only downside is that there is no what to perform a NOT operation. However, that could be reserved for the advanced search dialog. What does the list think about the BROADEN / NARROW button?
