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