Yes, thank you, that works!

But I first have to remove all dots from the user's search string, and then
insert "\.?" between all characters from this string.

If the user is searching for "M.G.M", I remove all dots and I get "MGM"
instead, and then I insert "\.?" between all characters and add one at the
end in order to obtain "M\.?G\.?M\.?"
Now Valentina can find "MGM", "M.G.M" or even "M.G.M."

Thanks to all for your precious help
