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