• If you are trying to use Boolean operators, they must be ALL CAPS: thu sach y ((((anh xay) OR (anh hay))) OR (dang xay)) hoi. hieu ve cam duc ban anh thai cua tre~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "thu sach y ((((anh xay) OR (anh hay))) or (dang xay)) hoi. hieu ve cam duc ban anh thai cua tre~".
• Adding a wildcard symbol may retrieve word variants: thu sach y ((((anh xay) OR (anh hay))) or (dang xay)) hoi. hieu ve cam duc ban anh thai cua tre*.
