long tail » long haul
tuan hua » tuan vu, yuan hui

• If you are trying to use Boolean operators, they must be ALL CAPS: ((wang liang) OR (wang yan)) ((tuan hua) OR (tan hua)) rents das clan long tail ;~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((wang liang) or (wang yan)) ((tuan hua) OR (tan hua)) rents das clan long tail ;~".
• Adding a wildcard symbol may retrieve word variants: ((wang liang) or (wang yan)) ((tuan hua) OR (tan hua)) rents das clan long tail ;*.
