• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) or (vu sach)) ky lang ha hoi. hieu van cao suc va ((thanh nam) OR (hanh nam)) va triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (vu sach)) ky lang ha hoi. hieu van cao suc va ((thanh nam) OR (hanh nam)) va triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) or (vu sach)) ky lang ha hoi. hieu van cao suc va ((thanh nam) OR (hanh nam)) va triet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) or (vu sach)) ky lang ha hoi. hieu van cao suc va ((thanh nam) OR (hanh nam)) va triet*.
