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