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.

Gradus autem stellarum sic quidem obviantium aut testimonium perhibentium auferunt solum annos aut eos addunt his qui ab apheta collecti sunt usque ad apheta occasum, non autem interficiunt eo quod non ipse stelle ad apheticum locum deferantur, sed ille ad ipsas et benefice quidem addunt auferunt autem malefice, Mercurius vero his addit stellis cum quibus fuerit figuratus.
