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