• Performing a fuzzy search may retrieve terms with similar spellings: ((vu sach) or (vu khach)) ((ky dang) OR (ky danh)) xa hoi. hieu ve cam duc va thanh vi cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((vu sach) OR (vu khach)) ((ky dang) OR (ky danh)) xa hoi. hieu ve cam duc va thanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((vu sach) or (vu khach)) ((ky dang) OR (ky danh)) xa hoi. hieu ve cam duc va thanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: ((vu sach) or (vu khach)) ((ky dang) OR (ky danh)) xa hoi. hieu ve cam duc va thanh vi cua te*.
