• Performing a fuzzy search may retrieve terms with similar spellings: tu ((sach ty) OR (sach tu)) ((xang ma) or (tang ma)) hoi. lieu va pham duy va thanh hai cua viet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach ty) OR (sach tu)) ((xang ma) OR (tang ma)) hoi. lieu va pham duy va thanh hai cua viet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach ty) OR (sach tu)) ((xang ma) or (tang ma)) hoi. lieu va pham duy va thanh hai cua viet".
• Adding a wildcard symbol may retrieve word variants: tu ((sach ty) OR (sach tu)) ((xang ma) or (tang ma)) hoi. lieu va pham duy va thanh hai cua viet*.
