• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach tu) OR (sach thu)) nang ma hoa. lieu va cam ((xuc va) or (duc va)) hanh tai cau treo~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (sach thu)) nang ma hoa. lieu va cam ((xuc va) OR (duc va)) hanh tai cau treo.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (sach thu)) nang ma hoa. lieu va cam ((xuc va) or (duc va)) hanh tai cau treo".
• Adding a wildcard symbol may retrieve word variants: thu ((sach tu) OR (sach thu)) nang ma hoa. lieu va cam ((xuc va) or (duc va)) hanh tai cau treo*.
