Perhaps you should try some spelling variations:
основіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основные\\" (Expand Search), основііе\\" (Expand Search), основеіе\\" (Expand Search)
основіеіееа\" » основііееа\" (Expand Search), основеіееа\" (Expand Search), основныеіееа\" (Expand Search), основііеіееа\" (Expand Search), основеіеіееа\" (Expand Search)
основіеіееа\\" » основііееа\\" (Expand Search), основеіееа\\" (Expand Search), основныеіееа\\" (Expand Search), основііеіееа\\" (Expand Search), основеіеіееа\\" (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 (основіеіееа\\" OR основіеіееа\\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основіе\ OR (основіеіееа OR основіеіееа\ ))) OR (\ ґрунтова основ\ )).
