Searching with Regular Expressions

For technically adept users, Citavi supports searching with regular expressions (regex). See for an introduction to regular expressions, and refer to for more detailed information.

When performing regex searches, prefix the search terms with RX . For example, to search for Meier, Maier, Meyer and Mayer, enter:

Be sure to type RX_ in capital letters so that Citavi can recognize it as a command. You can use regular expressions in both quick and advanced searches. You can also combine standard Citavi search syntax with regular expressions. For example, you can search for "M[ae][iy]er" in person fields and also search for "Edited Book" in reference type fields.

If your regular expression contains parentheses or spaces, you must place the entire regular expression, including the "RX_" prefix in quotation marks

Search options: Regex searches respect the A=a (Ignore case) option. The Whole word only and Allow spelling variations (ä=ae) options are ignored in a regex search. If necessary, provide the necessary conditions or equivalencies in the regular expression itself:

"RX_\binfo\b" finds "info" as a word, but not "information"
"RX_Z(u|ü)rich"finds "Zurich" and "Zürich"

Wildcards: During a regex search, the ? and * wildcards have their normal regex meanings and are not interpreted as wildcards.
