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