Perhaps you should try some spelling variations:
основіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основные\\" (Expand Search), основііе\\" (Expand Search), основеіе\\" (Expand Search)
основіеа\\" » основіа\\" (Expand Search), основеа\\" (Expand Search), основныеа\\" (Expand Search), основі\\" (Expand Search), основе\\" (Expand Search), основііеа\\" (Expand Search), основеіеа\\" (Expand Search)
основііеіеа\\" » основіііеіеа\\" (Expand Search), основеііеіеа\\" (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 (основіеа\\\" OR основііеіеа\\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основіе\ OR (основіеа\ OR основііеіеа\ ))) OR (\ ґрунтова основ\ )).
