What do the keywords “~” and "!~" signify in a filter condition?

The keywords “” and "!" in a filter condition are used to signify text operations within the context of searching or filtering data. The tilde symbol (“~”) indicates that the filter should return items that contain the specified text, thus allowing for partial matches and substring searches within the target data. This means that any item that has the designated text as part of its content will be included in the results.

On the other hand, the exclamation mark followed by the tilde ("!~") denotes the opposite condition, which filters out any items that contain the specified text. This means that the results will only show items that do not have the specified text in their content.

Understanding these operators is crucial for effectively creating and applying filters when analyzing logs and data within Fortinet FortiAnalyzer, ensuring that users can retrieve the precise information they need or exclude irrelevant data effectively.
