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