• Performing a fuzzy search may retrieve terms with similar spellings: thu cach thuc ((nano bac) or (hang ban)) hoi. hieu ve cam luc va ((kinh tri) OR (dinh tri)) cua te~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu cach thuc ((nano bac) OR (hang ban)) hoi. hieu ve cam luc va ((kinh tri) OR (dinh tri)) cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu cach thuc ((nano bac) or (hang ban)) hoi. hieu ve cam luc va ((kinh tri) OR (dinh tri)) cua te*".
