• Removing quotes may allow a broader search: (((( co hoi duc snippets ) OR ( python using java snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("co hoi duc snippets") OR ("python using java snippets"))) OR ("locating bugs code snippets"))*.
