• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ((ky tang) OR (kho tang)) lai hoi. hieu ((vu chao) OR (vu cao)) xu va hanh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ((ky tang) OR (kho tang)) lai hoi. hieu ((vu chao) or (vu cao)) xu va hanh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu sac ((ky tang) OR (kho tang)) lai hoi. hieu ((vu chao) or (vu cao)) xu va hanh vi cua te*.
