• If you are trying to use Boolean operators, they must be ALL CAPS: thu san ((ky lang) OR (ky dang)) mai hoi. hieu va chat ((xuc ban) OR (cuc ban)) hanh vi cua te*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu san ((ky lang) OR (ky dang)) mai hoi. hieu va chat ((xuc ban) or (cuc ban)) hanh vi cua te*".
