Perhaps you should try some spelling variations:
основііе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіііе\\" (Expand Search), основеііе\\" (Expand Search)
основііеіе\" » основііе\" (Expand Search), основеіе\" (Expand Search), основнііе\" (Expand Search), основіііеіе\" (Expand Search), основеііеіе\" (Expand Search)
основеіе\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіеіе\" (Expand Search), основееіе\" (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 (основііе\\\" OR (основеіе\\" OR основііеіе\\"))) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основііе\ OR (основеіе OR основііеіе ))) OR (\ ґрунтова основ\ ))~.
