• Performing a fuzzy search may retrieve terms with similar spellings: ((su sach) OR (so sach)) tay lang xa hoi. hieu ((ve cam) or (ve cham)) xuc va tich va cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((su sach) OR (so sach)) tay lang xa hoi. hieu ((ve cam) OR (ve cham)) xuc va tich va cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((su sach) OR (so sach)) tay lang xa hoi. hieu ((ve cam) or (ve cham)) xuc va tich va cua viet".
• Adding a wildcard symbol may retrieve word variants: ((su sach) OR (so sach)) tay lang xa hoi. hieu ((ve cam) or (ve cham)) xuc va tich va cua viet*.
