User story #113
Add information pop-up after filter input field in search
For now, the user don't now what he can look for in the composed search field.
We have to append a description after each filter, function of criterion type, to explain what is awaited.
Eg : date format is "dd/MM/YYYY", or "use '*' as a joker", or "you can use a unit for memory size like 300 Mo"
It's quite important, it is the kind of details that make the difference between a good and an awesome form
