• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y lang) or (tay lang)) xa hoi. hieu va cham cuu ((va hang) OR (van hang)) tai cuc te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y lang) OR (tay lang)) xa hoi. hieu va cham cuu ((va hang) OR (van hang)) tai cuc te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y lang) or (tay lang)) xa hoi. hieu va cham cuu ((va hang) OR (van hang)) tai cuc te".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y lang) or (tay lang)) xa hoi. hieu va cham cuu ((va hang) OR (van hang)) tai cuc te*.
