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