• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ky) OR (sach y)) nang ma hoi. ((hieu ve) or (lieu va)) cau tuc va thanh ha cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach y)) nang ma hoi. ((hieu ve) OR (lieu va)) cau tuc va thanh ha cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach y)) nang ma hoi. ((hieu ve) or (lieu va)) cau tuc va thanh ha cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach y)) nang ma hoi. ((hieu ve) or (lieu va)) cau tuc va thanh ha cua te*.
