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.

‘Claudii Ptolomei liber quem fructus appellant interprete Georgio Trapezontio. <I>am pridem perutiles ad previdendum operationes stellarum, o Syre, quas in hoc composito efficiunt mundo exposuimus… Abs te et a scientia, non est enim possibile ut huius scientie professor particulares rerum ideas prevideat — Sin vero non moventur hostis indigena erit. Finis. Deo gracias.’
