• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ty ((nang xa) OR (nang x)) hoi. ((lieu va) or (thi van)) lam trang va tinh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ty ((nang xa) OR (nang x)) hoi. ((lieu va) OR (thi van)) lam trang va tinh vi cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ty ((nang xa) OR (nang x)) hoi. ((lieu va) or (thi van)) lam trang va tinh vi cua triet*".
