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