The British Musical Biography

You have two options:

exact search
This returns entries whose last nime is precisely the term you enter.
For example, an exact search for 'Smith', will give you all entries with last name 'Smith'.
fuzzy' search
This also finds entries who's last names are spelled or sound close to what you enter.
For example, a fuzzy search for 'Smith' will also include 'Ethel Smyth' (at the end of the results)

At present only last name searches are supported
