• If you are trying to use Boolean operators, they must be ALL CAPS: vu sac ky sang ma hoi. hieu ((ve cam) OR (va cac)) ((luc va) OR (loc va)) hanh dai cua vat*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sac ky sang ma hoi. hieu ((ve cam) or (va cac)) ((luc va) OR (loc va)) hanh dai cua vat*".
