• The words AND, OR and NOT may confuse the search; try adding quotes: "\"\\"((\\\"ґрунтова (основеіе\\\" OR (основііе\\\" OR основеіееіеіе\\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основеіе\ OR (основііе\ OR основеіееіеіе\ ))) OR (\ ґрунтова основ\ )).
