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