• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty ((nang xa) OR (lang xa)) hoi. hieu va chat ((tuc va) OR (tuc xa)) hanh hoi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty ((nang xa) OR (lang xa)) hoi. hieu va chat ((tuc va) or (tuc xa)) hanh hoi cua te".
