• If you are trying to use Boolean operators, they must be ALL CAPS: te sac ky tang ma hoi. hieu ((ve cac) OR (va cac)) ((loc va) OR (thuc vat)) hanh lai chau tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sac ky tang ma hoi. hieu ((ve cac) OR (va cac)) ((loc va) or (thuc vat)) hanh lai chau tre*".
