• Performing a fuzzy search may retrieve terms with similar spellings: toc sach ky ((nang xa) or (nang ma)) hoi. hieu ((van thai) OR (van hai)) son gia thanh dinh cuu tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ky ((nang xa) OR (nang ma)) hoi. hieu ((van thai) OR (van hai)) son gia thanh dinh cuu tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ky ((nang xa) or (nang ma)) hoi. hieu ((van thai) OR (van hai)) son gia thanh dinh cuu tre".
• Adding a wildcard symbol may retrieve word variants: toc sach ky ((nang xa) or (nang ma)) hoi. hieu ((van thai) OR (van hai)) son gia thanh dinh cuu tre*.
