• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ly) OR (sach ty)) lang xa hoi. hieu ve ((chat tuc) OR (chat huu)) va hanh doi cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ly) or (sach ty)) lang xa hoi. hieu ve ((chat tuc) OR (chat huu)) va hanh doi cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ly) or (sach ty)) lang xa hoi. hieu ve ((chat tuc) OR (chat huu)) va hanh doi cua tre*.
