Subject: Split the search into values

Before, the search was a single value.
Now it is splited in chuncks when separated by spaces.
Except if they are enclosed by single quotes or double quotes.

For some reasons, the unit tests are working for both single and double quotes but the
search box isn't. It is working only with single quotes.
We need to investigate the reason of this behavior.

See #823
