• If you are trying to use Boolean operators, they must be ALL CAPS: te dac ((khoa tieng) OR (thoai tieng)) xa hoi. hieu ve cham xuc va dan ((lai cua) OR (hoi cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te dac ((khoa tieng) OR (thoai tieng)) xa hoi. hieu ve cham xuc va dan ((lai cua) or (hoi cua)) te".
• Adding a wildcard symbol may retrieve word variants: te dac ((khoa tieng) OR (thoai tieng)) xa hoi. hieu ve cham xuc va dan ((lai cua) or (hoi cua)) te*.
