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