_ (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.

‘<D>ixit Ptholomeus: Iam scripsi tibi, Yesure, et libros de hoc quod operantur stelle in seculo… Scientia stellarum ex te et illis est… Quod dixit Ptholomeus, ex te et illis, significat quod qui res futuras — (62rb) quanto melius qui vivimus (!) exposuimus. Pth<olome>us: Iste cum caudis sunt VIIII — in regibus et in divitibus apparebit. Et non intelligas solum hoc multis terris sed etiam in aliis secundum divisionem signorum quia diversa super diversas regiones habent signare. Explicit Centologium (!) Ptholomei commentatum ab Hely philosopho.’
