• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (vu sach)) ty lang ha hoi. hieu ((van cam) or (van nam)) hoc va thanh ve cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ty lang ha hoi. hieu ((van cam) OR (van nam)) hoc va thanh ve cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (vu sach)) ty lang ha hoi. hieu ((van cam) or (van nam)) hoc va thanh ve cau treo".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (vu sach)) ty lang ha hoi. hieu ((van cam) or (van nam)) hoc va thanh ve cau treo*.
