Regular expressions
The Princeton Geniza Project database allows for search expressions containing certain 'regular expressions'. Regular expressions are codes that can be inserted in search queries to match patterns of text.
| ^string | Matches the text at the beginning of the string |
| string$ | Matches the text at the end of the string |
| . | Matches any single character (including special characters) |
| a* | Matches the sequence of zero or more of the specified character |
| a+ | Matches the sequence of one or more of the specified character |
| a? | Matches zero or one occurrence of the specified character |
| abc|def | Matches either one of the specified strings |
| [abc] | Matches any one of the specified characters |
Boolean Search
The Princeton Geniza Project database uses a boolean full-text search. This type of search allows users to combine keywords with operators to refine searches. Possible operators and examples of their use:
| מולאנא מולאי | Search for rows that contain either of two words by simply typing them consecutively. In this case, the search will find documents that contain either מולאי or מולאנא. |
| כתאבי +מולאי+ | Use a + sign before word to search for rows that contain all of them (in this case the words כתאבי and מולאי) |
| כתאבי AND מולאי כתאבי OR מולאי | The keyword AND indicates that both search terms must be present in the results. OR matches either search term. |
| כתאב –כתאבה | Use a - sign to exclude a term from your results (in this case, the search will include כתאב but exclude כתאבה) |
| *כתאב ?כתאב |
Use an asterisk or a question mark as a wildcard. An asterix matches any number of characters. A question mark matches any single character |
T-S Ar.38.118
Letter in calligraphic Arabic script. The sender's name probably appears at upper left. He is writing from Jerusalem (al-Quds al-Mubārak, 6 lines from the bottom). The addressee is a woman (sittī al-karīma(?)). Possibly a letter of thanks, but might be a petition for further help. Includes a quotation from the Hebrew Bible (including Proverbs 13:19, תאוה נהיה תערב לנפש) transcribed into Arabic script (on which basis Khan identified the sender and addressee as Qaraites). In the margins and between the lines of recto and on verso there are Hebrew pen trials including biblical verses, and a few words in Arabic script copied from the text of the letter. Needs further examination for content. Cited in the literature only in two articles by Khan, where he refers to its existence but does not discuss its content.
