_ (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.

‘Claudii Ptolaemei (!) liber de analemate. Consideranti mihi, o Syre, angulorum acceptorum in locum gnomonicum quid rationale et quid non, habitum quidem virorum illorum in lineis accidit admirari et in hiis et valde acceptare — horarii autem ad eum qui secundum verticem, descensivi autem ad horizontem. Habent autem et canones ita’ (followed by the table ‘Cancri principii horarum 13’).
