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