• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach tu) OR (cach tu)) nang xa hoi. hieu va cac lo van anh ((gia cua) OR (gian cua)) te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach tu) OR (cach tu)) nang xa hoi. hieu va cac lo van anh ((gia cua) or (gian cua)) te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach tu) OR (cach tu)) nang xa hoi. hieu va cac lo van anh ((gia cua) or (gian cua)) te*.
