Additional Parameters to a Pre-Defined Regular Expression Search Filter

When creating a pre-defined search filter, you can define a parameter field by using the expression $fieldname.

The value you enter in the parameter replaces $field. In our example, we chose $username as our expression, and typed admin into the User Name field. This caused the regular expression search to return admin users wherever $username was specified.

The maximum length for each $field is 25 characters. Regular expressions can be up to 4096 characters in length.

This feature applies only to the Use Exact Phrase search filter and Regular Expression search.
