• Performing a fuzzy search may retrieve terms with similar spellings: ((thu san) OR (thuy san)) ky nang x hoi. hieu ve ((cac duc) or (cao duc)) va hanh noi cua tu~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu san) OR (thuy san)) ky nang x hoi. hieu ve ((cac duc) OR (cao duc)) va hanh noi cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu san) OR (thuy san)) ky nang x hoi. hieu ve ((cac duc) or (cao duc)) va hanh noi cua tu".
• Adding a wildcard symbol may retrieve word variants: ((thu san) OR (thuy san)) ky nang x hoi. hieu ve ((cac duc) or (cao duc)) va hanh noi cua tu*.
