• Performing a fuzzy search may retrieve terms with similar spellings: su sach tu xang ((x hoi) OR (x ho)). hieu ((ve cac) or (va cam)) xuc ban thanh vi cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach tu xang ((x hoi) OR (x ho)). hieu ((ve cac) OR (va cam)) xuc ban thanh vi cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach tu xang ((x hoi) OR (x ho)). hieu ((ve cac) or (va cam)) xuc ban thanh vi cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach tu xang ((x hoi) OR (x ho)). hieu ((ve cac) or (va cam)) xuc ban thanh vi cua triet*.
