I don't think silently supporting a standard is a good way to work -- it
breaks validation and could be used in an exploit in the future. Any
search standard has to be concrete.

Yes, me too.

Both or either? For instance, if I search for "gnome power" do I expect
results that match gnome AND power, or all results that match gnome OR
power? I think most people expect AND, right?
Should the client side make this policy decision? For instance, mapping
"gnome power manager" into "gnome AND power AND manager"? This seems
like the best solution where we are allowing advanced users to use
"power NOT gnome" and let casual users just type search words.
What about supporting: AND, OR, NOT and no nesting (brackets)?

Yes, I don't really want the client or server filtering out duplicate
entries, this is the job of the backend. I agree this has to be done in
