• If you are trying to use Boolean operators, they must be ALL CAPS: (("nhung bai que van. noi dung uoc mo") OR ("nhung moi quan quang. hoc dan quoc mo"))~.
• Removing quotes may allow a broader search: (( nhung bai que van. noi dung uoc mo ) or ( nhung moi quan quang. hoc dan quoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (("nhung bai que van. noi dung uoc mo") or ("nhung moi quan quang. hoc dan quoc mo"))*.
