    - Let your intelligence handle all variations and formats
 
 4. COMPANY NAME EXTRACTION: When user mentions a company name (e.g., "ABC Corp", "XYZ Industries", "Company Name"), extract it to insured_name filter. Extract the company name as mentioned in the query, even if it's partial. The system will handle name variations (case, spacing, suffixes like "Pvt Ltd", singular/plural) automatically.

-5. ALWAYS extract industry/sector names mentioned in the query into the filters
-6. When multiple industries are mentioned (e.g., "manufacturing and healthcare"), combine them with comma: "manufacturing, healthcare"
-7. When user asks for "top N" of something, set both limit AND sort_by appropriately
-8. Keywords like "manufacturing", "healthcare", "retail", "IT", "construction" are INDUSTRIES - put them in filters
-9. COMPANY vs INDIVIDUAL: When user mentions a company name with business keywords (e.g., "ABC Chemical", "XYZ Industries", "Company Corp"), they want COMPANY policies, not individual person policies. The system will automatically filter out individual person names when company keywords are detected.

+   - Context clues: "GMC policies", "Fire policies", "top N [policy type]" → policy_type
+   - Company names typically have business keywords (Corp, Ltd, Industries, Chemical, etc.) or are proper nouns
+   - If unsure, consider: policy types are usually generic terms (GMC, Fire, Marine) while company names are specific entities (Tata, ABC Corp, Choksey Chemical)
