• If you are trying to use Boolean operators, they must be ALL CAPS: ((thu sach) OR (tu sach)) ly nang x hoi. hieu va cham soc va hanh ((di cua) OR (vai cua)) te~.
• Adding a wildcard symbol may retrieve word variants: ((thu sach) or (tu sach)) ly nang x hoi. hieu va cham soc va hanh ((di cua) or (vai cua)) te*.
