• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ly nang xa hoi. ((hieu ve) OR (hieu va)) ((cam xuc) OR (cao duc)) ban thanh lai cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ly nang xa hoi. ((hieu ve) OR (hieu va)) ((cam xuc) or (cao duc)) ban thanh lai cua te".
