• Performing a fuzzy search may retrieve terms with similar spellings: thu sach ty lang van hoe. hieu ((van dat) or (dan dat)) nuoc va tinh vi ((cua tu) OR (cua tuc))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty lang van hoe. hieu ((van dat) OR (dan dat)) nuoc va tinh vi ((cua tu) OR (cua tuc)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty lang van hoe. hieu ((van dat) or (dan dat)) nuoc va tinh vi ((cua tu) OR (cua tuc))".
• Adding a wildcard symbol may retrieve word variants: thu sach ty lang van hoe. hieu ((van dat) or (dan dat)) nuoc va tinh vi ((cua tu) OR (cua tuc))*.
