What is it?
The search and replace filter is designed to be able to replace text either in a standard plain text mode or by using PCRE Regex.
How is it used?
Add Text Filter Replace, Remove & Insert Search & Replace Text
The search and replace filter is similar to any search and replace field in a text editor. Include a word or string of text you would like to change, then leave the replace field blank if removing, or insert a new word or text string if you would like to replace it.
