• If you are trying to use Boolean operators, they must be ALL CAPS: ho ((hieu manh) OR (diep tinh)) - hanh ((trinh tam) OR (trinh cham)) dung duong anh tuan ban*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "ho ((hieu manh) or (diep tinh)) - hanh ((trinh tam) OR (trinh cham)) dung duong anh tuan ban*".
