• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ly nang xa hoi. hieu ve ((pham duc) OR (((cao duc) OR (giao duc)))) van thanh tri cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sach ly nang xa hoi. hieu ve ((pham duc) or (((cao duc) OR (giao duc)))) van thanh tri cua te".
• Adding a wildcard symbol may retrieve word variants: tu sach ly nang xa hoi. hieu ve ((pham duc) or (((cao duc) OR (giao duc)))) van thanh tri cua te*.
