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