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