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