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