• Performing a fuzzy search may retrieve terms with similar spellings: ((thu sach) or (tu sach)) ky nang xa hoi. hieu ve cac lo van anh giau ((cua tre) OR (cua triet))~.
• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ky nang xa hoi. hieu ve cac lo van anh giau ((cua tre) OR (cua triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "((thu sach) or (tu sach)) ky nang xa hoi. hieu ve cac lo van anh giau ((cua tre) OR (cua triet))".
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (tu sach)) ky nang xa hoi. hieu ve cac lo van anh giau ((cua tre) OR (cua triet))*.
