Perhaps you should try some spelling variations:
основіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основные\\" (Expand Search), основііе\\" (Expand Search), основеіе\\" (Expand Search)
основіеееееа\" » основіееееа\" (Expand Search), основеееееа\" (Expand Search), основныеееееа\" (Expand Search), основііеееееа\" (Expand Search), основеіеееееа\" (Expand Search)
основіееееа\\" » основіеееа\\" (Expand Search), основееееа\\" (Expand Search), основныееееа\\" (Expand Search), основііееееа\\" (Expand Search), основеіееееа\\" (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 (основіеееееа\\" OR основіееееа\\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основіе\ OR (основіеееееа OR основіееееа\ ))) OR (\ ґрунтова основ\ )).
