Improve the search engine
I think it could be very useful to improve the current search bar in Diaspora, allowing people to mix search about users and tags.
Example of request :
Search every posts with #tag1 and #tag2
Search every posts with #tag1 or #tag2
Search every posts with #tag1 but without #tag2
Search every posts of a user + combination of requests above
We have to find a syntax easy to understand by everyone. I think we should also allow the programming syntax, so for me, we could use "and", "or" and "not", and "&&", "||" and "!".
