Describe the bug
Since #4505, a 'composed keyword' search - or a single keyword with quotes - makes it case-sensitive, so that searching "toto tutu" would not match "Toto Tutu". It used to be the case before this PR.

If it's on purpose that's fine (I find it logical at least when you have only one word), but is there a switch to indicate we want the search to be case sensitive or not when searching for a particular order of words?
