• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu bach ha pa nguoi cong thong minh ) OR ( su sach ha me nguoi co thong (tin OR tinh) ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu bach ha pa nguoi cong thong minh ) or ( su sach ha me nguoi co thong (tin OR tinh) ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu bach ha pa nguoi cong thong minh ) or ( su sach ha me nguoi co thong (tin OR tinh) ))*.
