• Performing a fuzzy search may retrieve terms with similar spellings: te sach ty song cua hoi. hieu van lam luc ((((va danh) OR (va dan))) or (va hanh)) sai chau tre~.
• If you are trying to use Boolean operators, they must be ALL CAPS: te sach ty song cua hoi. hieu van lam luc ((((va danh) OR (va dan))) OR (va hanh)) sai chau tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "te sach ty song cua hoi. hieu van lam luc ((((va danh) OR (va dan))) or (va hanh)) sai chau tre*".
