add multi-tag views

[Caleb Davis]

In IRC schendje just reminded me about the multi-tag views that
would be awesome to have:

/tag/bunnies+fangs

May we please have this now?

BONUS: /u/superwoahdude/tag/bunnies - subscribe to a user's tags
BONUS: /u/superwoahdude+awesomewoahman - subscribe to combo of
users
BONUS: /u/superwoahdude+awesomewoahman/tag/bunnies - subscribe to a
tag from a combo of users
BONUS: /u/superwoahdude+awesomewoahman/tag/bunnies+fangs -
subscribe to the intersection of arbitrary lists of users and tags

Another thing I'm wondering about: how do you end up on these
pages? Besides of course manually editing the address.

[Caleb Davis]

good question. Have you seen how delicious does it?

`http://www.delicious.com/tag/water+apocalypse <http://www.delicious.com/tag/water+apocalypse>`_

They use these really intuitive tag-looking widgets that interlock
with each other

water+apocolypse, hilarious :)

Hm, regarding how you might end up at one of these, I imagine three
possibilities:


-  A user sets up some special "tag collections" that are just
   things they marked as one or more tags that they've highlighted
   together. Like maybe you have a lot of FOSS stuff, but some of it
   is photos at conferences, some of it is mockups, etc. In that case
   you might have a "foss + conferences" tag collection highlighted on
   your frontpage helping people find your tag collection stuff.
-  Constructing the URLs manually...
-  Search! We've been talking about search for a while. Why not
   search encompassing text, people, tags! maybe the UI like:

   Search! Text [lol cats dawg ]

   Users: [cwebber, caleb, freedeb ]

   Tags [water, apocolypse ]


The url for that could be like:

/search/?users=cwebber+caleb+freedeb&tags=water+apocolypse&text=lol+cats+dawg

Adding this feature would be fairly bitesized. Adding an actual UI for it would be more complex, but I would consider it "done" for this ticket to just add the ability to filter the query as such.
