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