_ (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.

Scientia stellarum ex te et ex illis est: Ex te quidem per vim anime intellectivam quando separatur anima ab affectu rerum exteriorum sicut heremite et epilemtici — ex aliqua civitate illius climatis. Quandoque apparet cometa ad modum stelle — in regibus et divitibus aparebit. Explicit memoriale Benđđ. (?) de verbis Ph<tolome>i.’
