_ (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.

‘In nomine Albuguafe in libro suo quem scientiarum electionem et verborum nominavit… (1v) Bonum quod fecerunt in eo quod video in eo illi qui perscrutati sunt… (2v) Ecce ubi primi capituli prime dictinctionis initium dedit. Bonum domine fuit quod sapientibus non deviantibus visum est — et honestum est ut ponamus hoc finem libro. Expleta est dictio 13 libri Almagesti et cum ea completur liber Ptolomei de disciplinalibus.’
