• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"using a java snippets\") OR (\"vi ung data slippers\"))) OR (\"locating bugs code snippets\"))~".
• Removing quotes may allow a broader search: (((( using a java snippets ) OR ( vi ung data slippers ))) OR ( locating bugs code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("using a java snippets") OR ("vi ung data slippers"))) OR ("locating bugs code snippets"))*.
