• If you are trying to use Boolean operators, they must be ALL CAPS: thu ((sach ty) OR (sach thu)) nang x ho. hieu ((ve cai) OR (va cam)) duc gia thanh ca cua te.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu ((sach ty) OR (sach thu)) nang x ho. hieu ((ve cai) or (va cam)) duc gia thanh ca cua te".
• Adding a wildcard symbol may retrieve word variants: thu ((sach ty) OR (sach thu)) nang x ho. hieu ((ve cai) or (va cam)) duc gia thanh ca cua te*.
