• The words AND, OR and NOT may confuse the search; try adding quotes: "((((\"dung luong code snippets\") OR (\"dung co code snippets\"))) OR (\"locating bug code snippets\"))~".
• Removing quotes may allow a broader search: (((( dung luong code snippets ) OR ( dung co code snippets ))) OR ( locating bug code snippets ))~.
• Adding a wildcard symbol may retrieve word variants: (((("dung luong code snippets") OR ("dung co code snippets"))) OR ("locating bug code snippets"))*.
