• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ky nang ma hoi. hieu ((((dan cach) OR (dan canh))) OR (van hac)) truc va danh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ky nang ma hoi. hieu ((((dan cach) OR (dan canh))) or (van hac)) truc va danh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: thu san ky nang ma hoi. hieu ((((dan cach) OR (dan canh))) or (van hac)) truc va danh doi cua tre*.
