+
+### Filtering by Package Relationships
+
+
+Trivy supports filtering vulnerabilities based on the relationship of packages within a project.
+This is achieved through the `--pkg-relationships` flag.
+This feature allows you to focus on vulnerabilities in specific types of dependencies, such as only those in direct dependencies.
+
+In Trivy, there are four types of package relationships:
+
+1. `root`: The root package being scanned
+2. `direct`: Direct dependencies of the root package
+3. `indirect`: Transitive dependencies
+4. `unknown`: Packages whose relationship cannot be determined
+
+The available relationships may vary depending on the ecosystem.
+To see which relationships are supported for a particular project, you can use the JSON output format and check the `Relationship` field:
+
+```
+$ trivy repo -f json --list-all-pkgs /path/to/project
+```
+
+To scan only the root package and its direct dependencies, you can use the flag as follows:
+
+```
+$ trivy repo --pkg-relationships root,direct /path/to/project
+```
+
+By default, all relationships are included in the scan.
+
+!!! info
+    This flag filters the packages themselves, so it also affects the `--list-all-pkgs` option and SBOM generation.
+
+!!! warning
+    As it may not provide a complete package list, `--pkg-relationships` cannot be used with `--dependency-tree`, `--vex` or SBOM generation.
