      The modifier works by searching for a regular expression. For each match, it will replace it with another string.

      Both the regular expression and the replace text are written in the Latin-1 (ISO-8859-1) character set. However, because this modifier is intended for binary searches, most (if not all) characters should be written in hex using the \x escape.

      The Replace With text field supports the $1 $2… $n markers, to include portions of matched regular expressions in the replacement. This provides the ability to create advanced filters. For example, if the regular expression is (\d+)\x20(\d+) and the replacement string is $2\x20$1, then the filter will search for two numbers separated by a space character and swap the numbers.
