• If you are trying to use Boolean operators, they must be ALL CAPS: su ((sac ky) OR (cac ky)) dang xa hoi. hieu van ((bao suc) OR (bao thuc)) va phan lap cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su ((sac ky) OR (cac ky)) dang xa hoi. hieu van ((bao suc) or (bao thuc)) va phan lap cua triet".
• Adding a wildcard symbol may retrieve word variants: su ((sac ky) OR (cac ky)) dang xa hoi. hieu van ((bao suc) or (bao thuc)) va phan lap cua triet*.
