• If you are trying to use Boolean operators, they must be ALL CAPS: ((te sang) OR (te bang)) ky nang xa hoi. hieu van lam truong va han ((tai su) OR (lai su)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "((te sang) or (te bang)) ky nang xa hoi. hieu van lam truong va han ((tai su) OR (lai su)) triet".
• Adding a wildcard symbol may retrieve word variants: ((te sang) or (te bang)) ky nang xa hoi. hieu van lam truong va han ((tai su) OR (lai su)) triet*.
