_ (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.

‘Mundanorum ad hoc et ad illud mutatio corporum celestium mutatione… Scientia stellarum et rerum ex te et illis est. Astrologus non debet dicere rem specialiter sed universaliter… Quod dixit Pto<lomeus>, ex te et illis, significat quod qui res futuras prenoscere desiderat — dabit ei quod significat ex bono sive malo.’
