• Performing a fuzzy search may retrieve terms with similar spellings: va san ky nang xa hoi. ((hieu hien) or (hieu ve)) ((cap nuoc) OR (dat nuoc)) van hanh vai cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: va san ky nang xa hoi. ((hieu hien) OR (hieu ve)) ((cap nuoc) OR (dat nuoc)) van hanh vai cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "va san ky nang xa hoi. ((hieu hien) or (hieu ve)) ((cap nuoc) OR (dat nuoc)) van hanh vai cua te*".
