Great question!
If your user sessions are anonymous (eg. User 1234), you can generate a search for sessions based on a specific text string that you'd expect the user to enter within their session.
For example, if a user inputs their email address in order to sign into your application, you can search for when a user changed that exact text.
The example search provided above should return any sessions where a user typed test.user@gmail.com on your website.
Keep in mind, we index text changes exactly as the end-user entered them on your website. This means that the text is case sensitive when searching for "Changed Text is."
