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