• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"tu sach chep ve gioi can dong kinh\") OR (\"tu sach cha me gioi cat khong minh\"))~".
• Removing quotes may allow a broader search: (( tu sach chep ve gioi can dong kinh ) OR ( tu sach cha me gioi cat khong minh ))~.
• Adding a wildcard symbol may retrieve word variants: (("tu sach chep ve gioi can dong kinh") OR ("tu sach cha me gioi cat khong minh"))*.
