• Performing a fuzzy search may retrieve terms with similar spellings: thu ((sach tu) OR (sach thu)) ((mang may) or (nang ma)) hoi. hieu ve cam luc va hanh via cua tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (sach thu)) ((mang may) OR (nang ma)) hoi. hieu ve cam luc va hanh via cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (sach thu)) ((mang may) or (nang ma)) hoi. hieu ve cam luc va hanh via cua tre*".
