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