• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach duy) OR (sach dung)) ((can lai) or (can lay)) hoi. hieu su kham xuc gia thanh do cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach duy) OR (sach dung)) ((can lai) OR (can lay)) hoi. hieu su kham xuc gia thanh do cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach duy) OR (sach dung)) ((can lai) or (can lay)) hoi. hieu su kham xuc gia thanh do cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach duy) OR (sach dung)) ((can lai) or (can lay)) hoi. hieu su kham xuc gia thanh do cua te*.
