• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach tu) OR (cach tu)) nang xa hoi. hieu qua cam xuc va lang ((du cua) OR (duy cua)) te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach tu) or (cach tu)) nang xa hoi. hieu qua cam xuc va lang ((du cua) OR (duy cua)) te*".
