• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach ty)) dang tay hoi. hieu ve cam xuc ((may dinh) OR (my dinh)) ve cua triet*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) or (sach ty)) dang tay hoi. hieu ve cam xuc ((may dinh) OR (my dinh)) ve cua triet*".
