• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty hang van hoi. lieu va cac toc va ((nang di) OR (hang di)) ((cua triet) OR (va triet)).
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty hang van hoi. lieu va cac toc va ((nang di) OR (hang di)) ((cua triet) or (va triet))".
