• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky nang ma hoi. hieu he nam ((thu va) OR (tu va)) danh ((sai cua) OR (hai cua)) tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky nang ma hoi. hieu he nam ((thu va) OR (tu va)) danh ((sai cua) or (hai cua)) tre".
