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