• If you are trying to use Boolean operators, they must be ALL CAPS: su sai ky dang xa hoi. hieu ve cam ((duc manh) OR (suc manh)) hanh ((tai cua) OR (thai cua)) triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sai ky dang xa hoi. hieu ve cam ((duc manh) OR (suc manh)) hanh ((tai cua) or (thai cua)) triet".
• Adding a wildcard symbol may retrieve word variants: su sai ky dang xa hoi. hieu ve cam ((duc manh) OR (suc manh)) hanh ((tai cua) or (thai cua)) triet*.
