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