• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y tang ma hoi. lieu va ((cac xuc) OR (cam xuc)) va dinh ca ((cuu tre) or (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y tang ma hoi. lieu va ((cac xuc) OR (cam xuc)) va dinh ca ((cuu tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y tang ma hoi. lieu va ((cac xuc) OR (cam xuc)) va dinh ca ((cuu tre) or (cua triet))".
• Adding a wildcard symbol may retrieve word variants: tu sach y tang ma hoi. lieu va ((cac xuc) OR (cam xuc)) va dinh ca ((cuu tre) or (cua triet))*.
