• Performing a fuzzy search may retrieve terms with similar spellings: vu sach v nang xa hoi. hieu ve cac truc van hang di ((cua triet) or (((su triet) OR (su tien))))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach v nang xa hoi. hieu ve cac truc van hang di ((cua triet) OR (((su triet) OR (su tien)))).
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach v nang xa hoi. hieu ve cac truc van hang di ((cua triet) or (((su triet) OR (su tien))))".
