• Performing a fuzzy search may retrieve terms with similar spellings: su ((sach ky) OR (sach y)) nang xa hoi. thien van ((lam dung) or (nam duoc)) ban thanh vang cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sach ky) OR (sach y)) nang xa hoi. thien van ((lam dung) OR (nam duoc)) ban thanh vang cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sach ky) OR (sach y)) nang xa hoi. thien van ((lam dung) or (nam duoc)) ban thanh vang cua tre".
• Adding a wildcard symbol may retrieve word variants: su ((sach ky) OR (sach y)) nang xa hoi. thien van ((lam dung) or (nam duoc)) ban thanh vang cua tre*.
