_ (the underscore) is the placeholder for exactly one character.
% (the percent sign) is the placeholder for no, one or more than one character.
%% (two percent signs) is the placeholder for no, one or more than one character, but not for blank space (so that a search ends at word boundaries).

At the beginning and at the end, these placeholders are superfluous.

Work C.1.1

Thebit Bencora
De hiis que indigent expositione antequam legatur Almagesti


‘(ed. Carmody) Incipit liber Thebit Benchorath de hiis que indigent expositione antequam legatur Almagesti. Equator diei est circulus maior qui describitur super duos polos orbis ― in oppositione Solis aut propinqui oppositioni erunt retrogradi. Expletus est liber Thebit filii Core de hiis que indigent expositione antequam legatur Almagesti.’
