• Performing a fuzzy search may retrieve terms with similar spellings: thu sac ky tang ha noi. hieu su ((cham vuc) or (cham cuu)) van tuan le ((cua tre) OR (cuu tre))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu sac ky tang ha noi. hieu su ((cham vuc) OR (cham cuu)) van tuan le ((cua tre) OR (cuu tre)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sac ky tang ha noi. hieu su ((cham vuc) or (cham cuu)) van tuan le ((cua tre) OR (cuu tre))".
• Adding a wildcard symbol may retrieve word variants: thu sac ky tang ha noi. hieu su ((cham vuc) or (cham cuu)) van tuan le ((cua tre) OR (cuu tre))*.
