• If you are trying to use Boolean operators, they must be ALL CAPS: (( su sach ca me gioi bon thong tin ) OR ( vu ((sach che) OR (sach thue)) vi gioi vu hoang minh ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( su sach ca me gioi bon thong tin ) or ( vu ((sach che) OR (sach thue)) vi gioi vu hoang minh ))~".
• Adding a wildcard symbol may retrieve word variants: (( su sach ca me gioi bon thong tin ) or ( vu ((sach che) OR (sach thue)) vi gioi vu hoang minh ))*.
