+   - User query: "It must be from China or India. Otherwise, it must not be blue or red."
+   - Metadata: { "color": {...}, "country": {...} }
+   - 
+   - Output: 
+   {
+        "logic": "or",
+        "conditions": [
+          {"key": "color", "value": "blue, red", "op": "not in"},
+          {"key": "country", "value": "china, india", "op": "in"},
+        ]
+   }
+
+7. **Final Output**:
+   - ONLY output valid JSON dictionary
   - NO additional text/explanations
+   - Json schema is as following:
