Ability to use asterisk as a prefix, not just a suffix

Ability to use asterisk as a wildcard in a search query not only after the prefix, but also before the sufix, e.g. to find a contact with only the email address [email protected] added (e.g. the contact in the "Emailed Contacts" folder), typing “*kowalski” in the search field should be enough, but currently the user has to type “a.kowa*”, for example to find it.
