• If you are trying to use Boolean operators, they must be ALL CAPS: tu sac ky danh ((mai hoi) OR (mai khoi)). lieu va chat ((xuc ban) OR (duc ban)) hang vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu sac ky danh ((mai hoi) OR (mai khoi)). lieu va chat ((xuc ban) or (duc ban)) hang vi cua te".
