• If you are trying to use Boolean operators, they must be ALL CAPS: hoc ((((hien sach) OR (thien hach))) OR (dien sach)) - canh manh cua bang cong quang quan cau~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "hoc ((((hien sach) OR (thien hach))) or (dien sach)) - canh manh cua bang cong quang quan cau~".
• Adding a wildcard symbol may retrieve word variants: hoc ((((hien sach) OR (thien hach))) or (dien sach)) - canh manh cua bang cong quang quan cau*.
