• Performing a fuzzy search may retrieve terms with similar spellings: thuat lanh ky ((nang o) OR (nang co)) hoi. lieu va cham duc va ((hanh ve) or (hang di)) so viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thuat lanh ky ((nang o) OR (nang co)) hoi. lieu va cham duc va ((hanh ve) OR (hang di)) so viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thuat lanh ky ((nang o) OR (nang co)) hoi. lieu va cham duc va ((hanh ve) or (hang di)) so viet".
• Adding a wildcard symbol may retrieve word variants: thuat lanh ky ((nang o) OR (nang co)) hoi. lieu va cham duc va ((hanh ve) or (hang di)) so viet*.
