• If you are trying to use Boolean operators, they must be ALL CAPS: tu sach ky dang xay hoi. hieu ((ve cam) OR (ve cac)) ((xuc ban) OR (duc van)) hanh di cuu tre~.
• Adding a wildcard symbol may retrieve word variants: tu sach ky dang xay hoi. hieu ((ve cam) or (ve cac)) ((xuc ban) or (duc van)) hanh di cuu tre*.
