• Removing quotes may allow a broader search: (((( using raw java snippets ) OR ( dai cong code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using raw java snippets") OR ("dai cong code snippets"))) OR ("locating bug code snippets"))*.
