• If you are trying to use Boolean operators, they must be ALL CAPS: toc sach ((tay lang) OR (tay tang)) xa hoi. thien van ((nam xua) OR (nam cua)) va anh va cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "toc sach ((tay lang) or (tay tang)) xa hoi. thien van ((nam xua) OR (nam cua)) va anh va cua tre*".
