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