_ (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.

‘Dictio secunda incipit cuius capitula sunt 13. Liber hic precepto Maimonis regis Arabum, qui regnavit in Baldach… (4rb) Almagestum Ptolomei Pheludensis [title in upper margin, apparently by another hand]. Capitulum primum in prologo. Bonum quod fecerunt in eo quod video illi qui perscrutati sunt… (5ra) Incipit Almagesti quem Ptolomeus Pheludensis de scientia stellarum motuum celestium conscripsit. Quidam princeps nomine Albuguafe in libro suo quem scientiarum electionem et verborum nominavit… (5va) Capitulum primum in quo huius scientie excellentiam et finem eius utilitatis dicam. Bonum domine fuit quod sapientibus non deviantibus visum est — per ipsum prolongationem et abreviationem, tunc iam sequitur et honestum est ut ponamus hoc finem libri. Explicit.’
