Perhaps you should try some spelling variations:
основіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основные\\" (Expand Search), основііе\\" (Expand Search), основеіе\\" (Expand Search)
основіееіеа\" » основіеіеа\" (Expand Search), основееіеа\" (Expand Search), основныееіеа\" (Expand Search), основііееіеа\" (Expand Search), основеіееіеа\" (Expand Search)
основіеіеа\\" » основііеа\\" (Expand Search), основеіеа\\" (Expand Search), основныеіеа\\" (Expand Search), основііеіеа\\" (Expand Search), основеіеіеа\\" (Expand Search)
основ\\" » основі\\" (Expand Search), основе\\" (Expand Search)

You may be able to get more results by adjusting your search query.

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