• If you are trying to use Boolean operators, they must be ALL CAPS: tu ((sach tu) OR (sach thu)) ((nang xa) OR (lang xa)) hoi. hieu va cham tuc va danh le cua te~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "tu ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu va cham tuc va danh le cua te~".
• Adding a wildcard symbol may retrieve word variants: tu ((sach tu) OR (sach thu)) ((nang xa) or (lang xa)) hoi. hieu va cham tuc va danh le cua te*.
