Why doesn't electronics.stackexchange.com have a search q/a (site wide) feature? Or am I missing it? I see the "Tags" search, but is q/a posters didn't create a tag for the specific word/phrase you are searching site for, it seems time consuming to try to find.
Even when a use does enter tag, it only allows one word tags, not multi-word tags, which makes even search via tag cumbersome. (unless I am missing how to do multiple keyword tags too. :)
