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