Regex Field Replacement Index Stage

The Regex Field Replacement index stage, introduced in Fusion 3.0, lets you match against a source field and append or overwrite that field or another one with a replacement string. It uses the java.util.regex library.

One notable feature is support for flags in the prefix of the pattern, such as (?iu)\w+ where the i flag means case-insensitive and u means Unicode-aware case folding. You can also configure the desired behavior when there is no match. Additionally, you can also use capture groups in your replacement configuration using $1 to denote the first capture group.
