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