When adding a filter one can chose between "Title starts with" or "Title contains".
When searching directly in collection (using the search "tool bar") the search criteria seems always to be "title starts with".  If the default would be a search on a string within the title we could have the best of both worlds: the search would return the title wether it starts with that string or wether it contains that string. It would save the user from needing to use filtering all the time.

it seems to do this already, unless I'm confused, if you use the search box which you get when you pull down the collection list.

Noticed the same here.
F.e. If I enter "dates" in the collection search box the title "50 first dates" is filtered.
