• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty ang xa hoi. hieu ve ((((cam duc) OR (nam duoc))) or (cao duc)) ban hanh vai cua thuoc~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ang xa hoi. hieu ve ((((cam duc) OR (nam duoc))) OR (cao duc)) ban hanh vai cua thuoc.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ang xa hoi. hieu ve ((((cam duc) OR (nam duoc))) or (cao duc)) ban hanh vai cua thuoc".
• Adding a wildcard symbol may retrieve word variants: te sach ty ang xa hoi. hieu ve ((((cam duc) OR (nam duoc))) or (cao duc)) ban hanh vai cua thuoc*.
