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