• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ky) OR (sach ty)) tang van hoc. hieu ve ((chat huu) OR (chao xu)) va danh vi cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ky) OR (sach ty)) tang van hoc. hieu ve ((chat huu) or (chao xu)) va danh vi cua te".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ky) OR (sach ty)) tang van hoc. hieu ve ((chat huu) or (chao xu)) va danh vi cua te*.
