• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ly nang ro hoi. hieu ((van dau) OR (van dao)) ((xuc va) OR (tuc va)) hanh di cua vat.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ly nang ro hoi. hieu ((van dau) or (van dao)) ((xuc va) OR (tuc va)) hanh di cua vat".
