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