+            **Search condition**.
+            You can search in attributes by using **"conditionType:"** modifier and **"conditionValue:"** modifier.
+            Eg.
+            The entry "conditionType:API" will result in a match with blocking conditions only if the conditionType is "API". Similarly, "conditionValue:test/1.0.0" will result in a match with blocking conditions only if the conditionValue is "test/1.0.0".
+            When you use "conditionType:API & conditionValue:test/1.0.0" as a combination, it will result in a match with blocking conditions only if both the conditionType is "API" and the conditionValue is "test/1.0.0".
+            If query attribute is provided, this returns the blocking conditions that match the specified attributes.
