Run a blog on blogger.com? Maybe made it bilingual? Maybe blog on different topics? Wondering how the URL for an RSS feed for e.g. two labels looks like? Asking how to see all articles matching two tags (labels)? Finding a keyword under one or more labels? Many things are possible. I'll show a few examples below. Maybe that is even interesting for the planet Debian folks. I happen to blog mostly in English about Debian topics. But sometimes I also want to post something in German only (e.g. about German tax software). It is discouraged to put the latter on planet-debian. Instead it can be published in the language specific planet feed. So instead of adding new tags, one could easily combine two labels: the one for language of the feed and the one for Debian related posts (e.g. debian+english or debian+german). Therefor this post goes to the Debian planet.
Search for combbined labels/tags
Say I want to view all postings related to the topics FOO and BAR. Then it is:
http://domain.tld/search/label/FOO+BAR OR http://domain.tld/search/?q=label:FOO+label:BAR
Be aware that labels are case sensitive and that more labels can be added. The examples below will show all postings related to the topics debian and n54l and xbmc:
It is also possible to search for all posts related to the topics FOO or BAR:
Say for example, you want to see all postings related to the topics logitech or toshiba, then it is:
To get back to the first example lets say, the feed shall contain all posts related to the topics FOO and BAR. Then it is:
http://domain.tld/feeds/posts/default/-/FOO/BAR/ OR http://domain.tld/feeds/posts/default?q=label:FOO+label:BAR
Respecitvely to show all feeds related to either of those topics use:
To get a feed of the example topics as shown above then would be:
http://www.wgdd.de/feeds/posts/default/-/debian/n54l/xbmc/ http://www.wgdd.de/feeds/posts/default?q=label:debian+label:n54l+label:xbmc http://www.wgdd.de/feeds/posts/default?q=label:logitech|label:toshiba
Coming back to planet Debian, below is a solution for a multi-lingual planet contribution (if both planets would exist):
There is much more possible. I'll just show two more examples. AND and OR can be combined ...
... and a keyword search can be added too:
