• Performing a fuzzy search may retrieve terms with similar spellings: tu sach ((y nang) OR (v nang)) ma hoi. hieu ve cham xuc ((van thanh) or (tuan anh)) dai cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ((y nang) OR (v nang)) ma hoi. hieu ve cham xuc ((van thanh) OR (tuan anh)) dai cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ((y nang) OR (v nang)) ma hoi. hieu ve cham xuc ((van thanh) or (tuan anh)) dai cua tre".
• Adding a wildcard symbol may retrieve word variants: tu sach ((y nang) OR (v nang)) ma hoi. hieu ve cham xuc ((van thanh) or (tuan anh)) dai cua tre*.
