• If you are trying to use Boolean operators, they must be ALL CAPS: (("nhung bai quan va. hoi dong hoc mot") OR ("phung thi duy van. van duong uoc mo"))~.
• Removing quotes may allow a broader search: (( nhung bai quan va. hoi dong hoc mot ) or ( phung thi duy van. van duong uoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (("nhung bai quan va. hoi dong hoc mot") or ("phung thi duy van. van duong uoc mo"))*.
