user based » cluster based
reduce cao » reduced cap, reduce tax, reduce carbon
user case » use case, user cost, per case

• If you are trying to use Boolean operators, they must be ALL CAPS: (( luis ((user case) OR (user based)) transfer reduce cao ) OR ( luis f sea transport _ macro )).
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( luis ((user case) OR (user based)) transfer reduce cao ) or ( luis f sea transport _ macro ))".
• Adding a wildcard symbol may retrieve word variants: (( luis ((user case) OR (user based)) transfer reduce cao ) or ( luis f sea transport _ macro ))*.
