What is the purpose of using "!" in text filter conditions?

The use of "!" in text filter conditions signifies the negation of a condition. When you incorporate "!" before a parameter or value, it indicates that the filter should return results that do not match the specified condition. For example, if you are filtering out logs based on the status and use "status != 'failed'", this would retrieve all log entries where the status is anything other than 'failed'.

This function of negation is essential in scenarios where you want to exclude certain data or focus on a subset that meets criteria contrary to the defined condition. Therefore, using "!" allows for more granular and tailored data filtering, enhancing the ability to analyze logs effectively.
