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