- Use for search:
- Normal search: Match the string given in the Search field
- Wildcards: The string can contain the wildcard characters
- ? (single character)
- * (any group of characters)
- Regular expression: The search string is interpreted as a MySQL regular expression, except some regular expressions, that are black-listed for technical reasons.
- Please see the MySQL regular expression documentation for details on how to use regular expressions
The following list contains the regular expressions which are not supported by translate5, because they are black-listed:

The code point shown here is an example. ex: \u78af \(\?\:.*?\) Non-capturing parentheses group the regex so you can apply regex operators, but do not capture anything. \(.*?\)=\\[0-9] (abc|def)=\1 matches abc=abc or def=def, but not abc=def or def=abc. \(\?\=.*?\) Matches at a position where the pattern inside the lookahead can be matched. Matches only the position. It does not consume any characters or expand the match. In a pattern like one(?=two)three, both two and three have to match at the position where the match of one ends. \(\?\!.*?\) Similar to positive lookahead, except that negative lookahead only succeeds if the regex inside the lookahead fails to match. \[\:(.*)\:\] The following table illustrates some commonly used metacharacters and constructs in a regular expression.
Metacharacter Behavior ^ matches the position at the beginning of the searched string $ matches the position at the end of the searched string […] matches any character specified inside the square brackets [^…] matches any character not specified inside the square brackets * matches the preceding character zero or more times + matches preceding character one or more times {n} matches n number of instances of the preceding character {m,n} matches from m to n number of instances of the preceding character
