_ (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.

= ʿAlī ibn Riḍwān‎‎, Abū l-Ḥasan ibn ʿAlī al-Miṣrī, Tafsīr al-Maqālāt al-arbaʿ fī l-qaḍāʾ bi-l-nujūm ʿalā l-ḥawādith (C.2.1050). — Title: Sharḥ al-Maqāla al-ūlā wa-l-thāniya wa-l-thālitha min Kitāb Baṭlamiyūs fī l-qaḍāʾ bi-l-nujūm (Ir). — Additional titles: Libro cumplido del philosopho Batlamayus alofludi de teorica Astronomie con comento de Abi lhacen ali aben redoan aben Jafar Elmedico (Iv). — Index: I.1 (=I), 1v-17r; I.2 (=II), 17v-33r; I.3 (=III), 33r-45v; II.1 (=IV), 46r-59r; II.2 (=V), 59v-75r; II.3 (=VI), 75r-86r; III.1 (=VII), 88v-101r; VIII (=III.2), 101r-113r; IX (=III.3), 113r-126r; X (=IV.1), 128r-140v; XI (=IV.2), 140v-153v; XII (=IV.3), 154r-161r. — The first nine books of Ibn Riḍwan’s commentary are written in Arabic in Arabic script, whilst the last three books which contain the commentary to Book IV of the Tetrabiblos are also in Arabic, but in cursive Sephardic Hebrew script. It is possible that the scribe of both parts is the same, despite his Muslim name, as in the part in cursive Sephardic script there are few words written in Arabic in the seemingly same hand as the section written in Arabic script (145r, 149v, 151v, 152v). The first seven books are numbered according to the book of the Tetrabiblos upon which they comment. Dated scribal colophons of Books II.3 (=VI) and IX (=III.3), and a non-dated scribal colophon of Book XII (=IV.3). Labels of diagrams describing horoscopes in the cursive Sephardic part, in Arabic script. Minor marginal corrections and no collations. Substantial glosses in Hebrew script through the entire manuscript. Minor glosses in Arabic script in at least two different hands and inks. Drawings of hands in margin pointing to interesting sections of the body text or to marginal glosses.
