It appears to be a combination of

following tags with logical expressions AND, NOT, OR

Is it possible to use a kind of logical expressions (AND, NOT, OR) to define "ta…gs i am following"? Example: i want to follow what is in my local city #bremen but i am not interested in soccer. unfortunately our local soccer team is tagged as "#werder #bremen". So if i follow #bremen i also get soccer news. I want to follow all #bremen that does not contain #werder. A possible syntax could be "#(bremen && !werder)" or "#(bremen AND NOT werder)" But perhaps there are ideas for a more intuitive syntax [update oct 16th, 05:13 gmt: added definitions; added summary of discussion ] I call this "logical expression"/the think we are discussing about a "filter". current limitations in diaspora (from @shmerl-s post) - User can only follow a straight list of tags (i.e. following is defined with logical OR). - User can’t filter tags for not following (i.e. not to see some content which has them). - Viewing options of followed tags in the UI are limited to either viewing all followed tags, or only one. 1) maingoal define an advanced filtering for diaspora "search" and "stuff i am following" 2) subgoal must be compatibel with current diaspora "search" and "stuff i am following" 3) subgoal a simple and limited filter syntax for non-coders that is as close to other existing filters as possible (i.e. groogle or stackoverflow) 4) subgoal an advanced powerfull filter syntax wich allows complex boolean expressions 4.1) make it easy to understand for noncoders, even if it is not easy to create 4.2) make it easy to create even if it is complex (i.e. using a kind of wizzard like this http://www.google.com/advanced_search ) (inspired by @Alienglyph-s post) We have to define elements that can be used in the filter (inspired by @Alienglyph-s post) a) #tagThatIsInsideThePost b) senderWhoWroteThePost c) commenterWhoAddedCommentToThePost d) @somoneBeeingReferenced e) someTextInThePost f) ageOfThePost (i.e. not older than one week) --- proposals for (3) simple filter - use " " as "AND" similar to google/stackoverflow (@k3b, @Alienglyph) - use prefix "-" as "AND NOT" i.e. "#a -#b" for "#a and not #b" similar to google/stackoverflow (@k3b) - use keyword ":except:" as "AND NOT" which supports (4.1) (@Alienglyph) - use prefix "\" i.e. "#a /#b" for "#a and not #b" similar to math (@Alienglyph) proposals for (4) advanced filter syntax -using c/java style !, &&, || and () contradicts (4.1) : @k3b, @Flaburgan -using keywords "AND", "OR", "NOT" and () : @shmerl, @Flaburgan -using keyword ":except:" as "AND NOT" which supports (4.1) (@Alienglyph) proposal for element syntax - create element prefix i.e. "#sender:someSenderName" (@Alienglyph) - create element prefix i.e. "@@someSenderName", "%@someCommenterName" (@shmerl) ##
