• If you are trying to use Boolean operators, they must be ALL CAPS: hoc sinh y ((nano xa) OR (nano bac)) hoi. hieu ve cam luc va dinh ((ve cua) OR (de cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc sinh y ((nano xa) OR (nano bac)) hoi. hieu ve cam luc va dinh ((ve cua) or (de cua)) te*".
