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.

Nihil autem interdum prohibet, cum dubitaverimus qui nam ii sint qui interficiendi dominatum debeant accipere, obviationes que ad unumquenque eorum fiunt considerantes, aut ea quae maxime cum praecedentibus accidentium speciebus conveniunt ad futura sequi, aut ad omnes velut secundum equalitatem potestatis valentes observationem habere quod magis est et minus eorum secundum eundem modum considerantes.
