• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky tang ((mai hoi) OR (mai khoi)). ((hieu ve) OR (hieu va)) cham xuc va xanh di cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky tang ((mai hoi) or (mai khoi)). ((hieu ve) OR (hieu va)) cham xuc va xanh di cua tre~".
• Adding a wildcard symbol may retrieve word variants: vu sac ky tang ((mai hoi) or (mai khoi)). ((hieu ve) OR (hieu va)) cham xuc va xanh di cua tre*.
