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