Ptolemaeus Arabus et Latinus

_ (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.

‘Incipit liber de iudiciis partium Ptolomei. Et primo de parte fortune, hic accipitur in die a Sole in Lunam, in nocte e converso, et proicitur ab ascendente. Quoniam in primo libro partium terminos et loca posuimus, iudicia sub earundem ministrare curavimus. Pars fortune et eius dominus corpus et que ad corpus attinent — partis significationem aut eius domini hiis 12 mensibus mutatur.’
