I think that forum rules about naming threads should be specified. That would improved search function.
Something like this:
"Always specify what is the problem of thread in the title.
Topic such us:
'n900 problem!!! zomg plz helpx me!' will be deleted.
Example of correct naming of thread:
'My n900 battery is dead' "

This would make more work for moderators, but it's not a problem to hire two or three more(?)
