Analyzing the Query Configuration exhibit in the context of FortiSIEM 7.3 search logic reveals several syntax and logical errors that prevent the query from returning results:

Logical Operator Error (E): The user intends to find traffic to Europe OR Asia. In the exhibit, the first row (Group: Europe) is followed by a default AND operator. This forces the query to look for a single flow where the destination is simultaneously in Europe and Asia, which is logically impossible. It must be changed to OR .

Missing Parentheses (C): When combining OR and AND logic in FortiSIEM, parentheses are required to define the order of operations. Without them, the query might evaluate " Asia AND Destination Country IS NOT null AND Source IP IN... " first. To correctly find (Europe OR Asia) that also matches the LAN segment, parentheses must group the first two rows.

Incorrect Operator for IP Range (D): The exhibit uses the IN operator for the value 10.0.0.0, 10.200.200.254. In FortiSIEM, the IN operator is used for a comma-separated list of specific values or CMDB groups. To specify a continuous range of IP addresses (the " LAN segment " ), the BETWEEN operator must be used.

Why other options are incorrect:

IS NOT null (A): In FortiSIEM, " IS NOT null " is a valid operator/value combination used to ensure a specific attribute has been successfully parsed and populated in the event record.

Time Range (B): There is no requirement for a time range to be " Absolute " when using CMDB groups; " Relative " time ranges (like the " Last 30 Days " shown) are commonly used and fully supported for such queries.
