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