Allow searching for multiple tags or omitting tags

[jacobgkau]

One of the reasons tags are supposed to be more useful than folders is that they can be combined. For example, I could have three links:

• Link 1: tag1, tag2
• Link 2: tag1, tag3
• Link 3: tag2, tag3

With this collection, I should be able to search "tag1 tag3" to have only Link 2 return. Currently, if I specify two tags, I get results that only contain one of the tags.

Similarly, I should be able to search e.g. "tag2 -tag1" and have only Link 3 return.

This would be extremely helpful and kind of necessary for tags to be useful. I was expecting the tag-searching functionality to behave this way and organized my bookmarks accordingly, but just now disappointingly found out that it doesn't.

I also think this would be THE most useful improvement for search. The search query should allow tagX AND tagY. Now it's tagX OR tagY which is does not help in any way.
