_ (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.

Explicit. [propositiones planisperii] Incipit prima propositio planisperii. Quoslibet duos circulos equidistantes recto in spera — (12r) per polum zodiaci transire necesse habet.
