• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach chat moi gioi con thong tin ) OR ( tu ((sach bo) OR (sach lo)) le nguoi o dong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach chat moi gioi con thong tin ) or ( tu ((sach bo) OR (sach lo)) le nguoi o dong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach chat moi gioi con thong tin ) or ( tu ((sach bo) OR (sach lo)) le nguoi o dong tin ))*.
