• If you are trying to use Boolean operators, they must be ALL CAPS: (("nhung thoi qua van. boi duong ngoc son") OR ("nhung bi quan van. hoc dung thuoc mo"))~.
• Removing quotes may allow a broader search: (( nhung thoi qua van. boi duong ngoc son ) or ( nhung bi quan van. hoc dung thuoc mo ))~.
• Adding a wildcard symbol may retrieve word variants: (("nhung thoi qua van. boi duong ngoc son") or ("nhung bi quan van. hoc dung thuoc mo"))*.
