• Performing a fuzzy search may retrieve terms with similar spellings: tu sach y sang ma hoi. hieu ((ve cham) or (va cam)) ((xuc van) OR (luc van)) hoan di su triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach y sang ma hoi. hieu ((ve cham) OR (va cam)) ((xuc van) OR (luc van)) hoan di su triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach y sang ma hoi. hieu ((ve cham) or (va cam)) ((xuc van) OR (luc van)) hoan di su triet".
