• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"sach thuong dan đoc truyen thong lanh\") OR (\"sach huong dan đoc truyen tuong lanh\"))~".
• Removing quotes may allow a broader search: (( sach thuong dan đoc truyen thong lanh ) OR ( sach huong dan đoc truyen tuong lanh ))~.
• Adding a wildcard symbol may retrieve word variants: (("sach thuong dan đoc truyen thong lanh") OR ("sach huong dan đoc truyen tuong lanh"))*.
