• Removing quotes may allow a broader search: (((( using java code snippets ) or ( hoang tran mo snippets ))) or ( locating bug core snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") or ("hoang tran mo snippets"))) or ("locating bug core snippets"))*.
