• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sac) OR (vu san)) ky danh van hoe. hieu ve ((cac luc) OR (coc luc)) va danh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sac) or (vu san)) ky danh van hoe. hieu ve ((cac luc) OR (coc luc)) va danh doi cua tre".
