• Removing quotes may allow a broader search: (((( dung cho code snippets ) OR ( dang tinh java snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung cho code snippets") OR ("dang tinh java snippets"))) OR ("locating bug code snippets"))*.
