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 |

Letter from Nissim b. Salāma to Abū Saʿd Khalaf b. Salāma. In Judaeo-Arabic. Concerning commercial matters, including a grocer ordering for his store one hundred pounds of raisins (zabib), and one wayba each (about twenty-three pounds) of rice and sesame. It seems that some of the rice will be supplied by Abū ʿImrān. Nissim then asks Abū Saʿd not to use Arabic script since he didn't know how to read it and had to trouble friends to read him the letters received and then would sometimes forget what he had heard. (Information from Goitein, Med Soc 2:179, 557 and 4:439.) Join: Oded Zinger.
