• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach ty tang ((ma hoi) OR (xa hoi)). ((lieu va) OR (lieu van)) cac vo van canh giac cua tre*.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach ty tang ((ma hoi) OR (xa hoi)). ((lieu va) or (lieu van)) cac vo van canh giac cua tre*".
