• If you are trying to use Boolean operators, they must be ALL CAPS: toc ((sach ky) OR (sach y)) nang xa hoi. ((lieu va) OR (hieu va)) cac xuc va tinh hoa cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc ((sach ky) OR (sach y)) nang xa hoi. ((lieu va) or (hieu va)) cac xuc va tinh hoa cua triet".
• Adding a wildcard symbol may retrieve word variants: toc ((sach ky) OR (sach y)) nang xa hoi. ((lieu va) or (hieu va)) cac xuc va tinh hoa cua triet*.
