• The words AND, OR and NOT may confuse the search; try adding quotes: "te ((sach ky) or (((sach ty) OR (sach thu)))) nang xa hoi. hieu va cam luc van tuan te cua tre~".
• Adding a wildcard symbol may retrieve word variants: te ((sach ky) or (((sach ty) OR (sach thu)))) nang xa hoi. hieu va cam luc van tuan te cua tre*.
