• Removing quotes may allow a broader search: (((( using java code snippets ) OR ( van anh tran snippets ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using java code snippets") OR ("van anh tran snippets"))) OR ("locating bugs code snippets"))*.
