- 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 table illustrates some commonly used metacharacters and constructs in a regular expression, that are allowed to use in translate5:
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 | matches string "a" or string "b" divided with the separator The following list contains the regular expressions and regular expressions, which are not supported by translate5, because they are black-listed:. Black-listing is done due to more effort in development, that would be needed to support them. If you are interested in having support for black-listed regexes, please contact the development team of MittagQI.
