• If you are trying to use Boolean operators, they must be ALL CAPS: (("nhung thoi que lang. boi duong hoc mot") OR ("nhung tri viet lang. hoc dang quoc co"))~.
• Removing quotes may allow a broader search: (( nhung thoi que lang. boi duong hoc mot ) or ( nhung tri viet lang. hoc dang quoc co ))~.
• Adding a wildcard symbol may retrieve word variants: (("nhung thoi que lang. boi duong hoc mot") or ("nhung tri viet lang. hoc dang quoc co"))*.
