_ (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.

Text

‘(ed. Thorndike) Tractatus de infusione spermatis secundum dominum Andelonem de Nigro de Ianua. Super verbo Centiloquii 51. Hester etiam Ptholomeus et Hermes dixerunt quod locus seu gradus signi in quo est Luna tempore infusionis spermatis est gradus ascendens in nativitate et quod gradus qui est ascendens in infusione spermatis, in dicto gradu illius signi erit Luna in tempore nativitatis. Dixerunt etiam Ptholomeus et Hermes quod cum Luna tempore infusionis spermatis est in ascendente, tunc mora nati in ventre matris est spatium 273 dierum et hec dicitur mora media… Ester Catayus habuit aliquam differentiam a Ptholomeo et Hermete… Sed Ptholomeus et Hermes dixerunt quod mora maior superabat mediam per dies 15… Dixerunt etiam quod planete qui dominabantur a conception usque ad nativitatem… Dixit Ester quod in omni conception necessaria sunt yles et alcocodeus acatzir — sicut quando aliquis planeta est alcocodeus mutatur mora ut capitulo alcocodei more dicitur.’
