• If you are trying to use Boolean operators, they must be ALL CAPS: vu sach ty xang xa hoi. hieu ((ve cac) OR (va cac)) ((duc van) OR (duc manh)) dinh tri cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "vu sach ty xang xa hoi. hieu ((ve cac) or (va cac)) ((duc van) OR (duc manh)) dinh tri cua te".
