• Performing a fuzzy search may retrieve terms with similar spellings: su sach ty ((((nang xa) OR (nang x))) or (nang cao)) hoi. thien van cam xuc nhan hang va cau tren~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach ty ((((nang xa) OR (nang x))) OR (nang cao)) hoi. thien van cam xuc nhan hang va cau tren.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach ty ((((nang xa) OR (nang x))) or (nang cao)) hoi. thien van cam xuc nhan hang va cau tren".
• Adding a wildcard symbol may retrieve word variants: su sach ty ((((nang xa) OR (nang x))) or (nang cao)) hoi. thien van cam xuc nhan hang va cau tren*.
