• Performing a fuzzy search may retrieve terms with similar spellings: su sach y ((((nang ma) OR (tang ma))) or (sang ma)) hoi. hieu va cam xuc xa hanh tai cua triet~.
• If you are trying to use Boolean operators, they must be ALL CAPS: su sach y ((((nang ma) OR (tang ma))) OR (sang ma)) hoi. hieu va cam xuc xa hanh tai cua triet.
• The words AND, OR and NOT may confuse the search; try adding quotes: "su sach y ((((nang ma) OR (tang ma))) or (sang ma)) hoi. hieu va cam xuc xa hanh tai cua triet".
• Adding a wildcard symbol may retrieve word variants: su sach y ((((nang ma) OR (tang ma))) or (sang ma)) hoi. hieu va cam xuc xa hanh tai cua triet*.
