Using Regular Expressions in Text Searches

Regular expressions can be used to search for some unspecified or even invisible characters.

note

Searching with regular expressions is different from searching with wildcards. LibreOffice Writer only supports searching with regular expressions.


You can use regular expressions when you find and replace text in a document. For example, "s.n" finds "sun" and "son".
