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