Searching words on the site can be better

Hello, when i search in the backhand for "profile" because i want another word instead.

I see a lot of keys... Too much to look to all the keys...

It's possible with some characters (e.g. /profil/) to chearch only the word profil?

What are they then if they exist?

You can also search on a string; which may help to narrow down the search results.
