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