_ (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.

‘Opus imaginum secundum consilium Ptholomei est omnibus modis veracius in probatione quoniam eius effectus constitutus est super facies signorum et est certissimum quomodo Albumasar et Arabici et omnes orientales operabantur cum eo — mali vero sint cadentes ab ea et finitur. Expliciunt imagines astronomice secundum Ptholomeum.’
