• If you are trying to use Boolean operators, they must be ALL CAPS: vu khac ky danh xa hoi. hieu van lam luc ((va thanh) OR (gia thanh)) ve ((cua tre) OR (cua tu)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu khac ky danh xa hoi. hieu van lam luc ((va thanh) OR (gia thanh)) ve ((cua tre) or (cua tu))".
• Adding a wildcard symbol may retrieve word variants: vu khac ky danh xa hoi. hieu van lam luc ((va thanh) OR (gia thanh)) ve ((cua tre) or (cua tu))*.
