- Require ALL core identifier words to be present in match
(e.g., "Lloyds Bowmaker" needs both "LLOYDS" and "BOWMAKER")
- Filter out club/association/society type entities
(prevents "BMW" -> "BMW CAR CLUB LIMITED")
- Filter out benefit/trust/pension type entities
(prevents "BMW Group" -> "BMW GROUP BENEFIT TRUST LIMITED")
- Core word extraction now returns all significant words, not just first
Fixes false matches like:
- "BMW Group Canada" -> "CANADA LIFE GROUP" (missing BMW)
- "Bank of Scotland" -> "BANK AND CLIENTS PLC" (missing Scotland)
- "Lloyds Bowmaker" -> "LLOYDS ALARMS" (missing Bowmaker)
