• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh ((ty nano) OR (day nano)) xa hoi. hieu ((ve cam) OR (va cam)) xuc va dinh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh ((ty nano) OR (day nano)) xa hoi. hieu ((ve cam) or (va cam)) xuc va dinh vi cua te".
• Adding a wildcard symbol may retrieve word variants: hoc sinh ((ty nano) OR (day nano)) xa hoi. hieu ((ve cam) or (va cam)) xuc va dinh vi cua te*.
