• If you are trying to use Boolean operators, they must be ALL CAPS: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve pham duc va ((dinh lam) OR (tinh lao)) cua tre.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve pham duc va ((dinh lam) or (tinh lao)) cua tre".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) OR (sac ky)) nang xa hoi. hieu ve pham duc va ((dinh lam) or (tinh lao)) cua tre*.
