• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty xang xa hoi. ((hieu va) OR (lieu va)) chat huu va ((hanh doi) OR (hanh noi)) cua tu.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty xang xa hoi. ((hieu va) or (lieu va)) chat huu va ((hanh doi) OR (hanh noi)) cua tu".
