• Performing a fuzzy search may retrieve terms with similar spellings: doc sach thi hanh xa hoi. hieu ((va chat) OR (van chat)) luoc van anh vi ((cua tre) or (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: doc sach thi hanh xa hoi. hieu ((va chat) OR (van chat)) luoc van anh vi ((cua tre) OR (cuu tre))*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "doc sach thi hanh xa hoi. hieu ((va chat) OR (van chat)) luoc van anh vi ((cua tre) or (cuu tre))*".
