• If you are trying to use Boolean operators, they must be ALL CAPS: (("nhung bai quen hanh. hai duong hoc mo") OR ("nhung thi hue lang. hoc dung hoc mo"))~.
• Removing quotes may allow a broader search: (( nhung bai quen hanh. hai duong hoc mo ) or ( nhung thi hue lang. hoc dung hoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (("nhung bai quen hanh. hai duong hoc mo") or ("nhung thi hue lang. hoc dung hoc mo"))*.
