The disqus.changed.* namespace family is populated when an interaction represents an update. You can regard this namespace family as a change log.
This target holds the previous text of a post or comment prior to an update.
The updated text is available for filtering in the top-level disqus.message target.
- Filter for content that used to mention red and not blue and now mentions blue and not red:
disqus.changed.message contains "red" and not disqus.changed.message contains "blue" and disqus.message contains "blue" and not disqus.message contains "red"
