With a Regex filter, you can define a regular expression to pass or not to pass data that is more powerful than the simple filter. A Regex Filter is similar to a Simple Filter but with this you can perform more complex searching and matching.
For more information about the regular expressions, and to build and test them, see https://regex101.com.
To add a Regex Filter, click the Regex Filter in the Add Process window. The canvas updates immediately to show the empty filter.
Specifying the Regular expression
All parts of the Regular expression are case-sensitive. For example, ‘PRODUCTION’, ‘Production’ and ‘production’ are all considered as different strings, and “STATUS”:”OK” and “Status”:”OK” will be considered as two different strings.
Example: To look for a string that contains “ERRORCODE”:” followed by a number, you can enter a regular expression of “ERRORCODE”:\d. \d string identifies “a number”.
