• If you are trying to use Boolean operators, they must be ALL CAPS: (( tu sach pha ve gioi bon thong tin ) OR ( ((su sach) OR (vu sach)) nha ma nguoi moi thong tin ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( tu sach pha ve gioi bon thong tin ) or ( ((su sach) OR (vu sach)) nha ma nguoi moi thong tin ))~".
• Adding a wildcard symbol may retrieve word variants: (( tu sach pha ve gioi bon thong tin ) or ( ((su sach) OR (vu sach)) nha ma nguoi moi thong tin ))*.
