+        A SQL-like query string to filter the list of entities. The query supports rich filtering capabilities with automatic type inference.

+        **Supported Operators:**
+        - Comparison: `=`, `!=`, `<>`, `>`, `<`, `>=`, `<=`
+        - Pattern matching: `LIKE`, `ILIKE` (case-insensitive)
+        - Set membership: `IN`
