If you’ve used del.icio.us you probably know that you can search for example for items that have tag “a” and tag “b” by simply combining them with a “+”. For example http://del.icio.us/zerok/book+webdesign would give you a listing of all items that I’ve tagged with both tags.
I’ve now searched the documentation on ma.gnolia for some information on a similiar feature and couldn’t find anything. Linking the tags with “+” doesn’t work, so what now? Well, considering that you enter the tags when adding a new bookmark by concaternating multiple tags with “,” it was my next try. And voilß , “,” does the job :) So to stay with the example above, http://ma.gnolia.com/people/zeroK/tags/book,webdesign should give you the same result as the del.icio.us link above :)
On a sidenote: In my opinion it would be cool, to expand this idea and add “;” as junktor to symbolize and OR and perhaps also other special characters to get XOR ("?") and WITHOUT ("").
Note: URL-encoding was omitted to keep the examples better readable :)
