Perhaps you should try some spelling variations:
основніе\" » основні\" (Expand Search), основные\" (Expand Search), основі\" (Expand Search), основініе\" (Expand Search), основеніе\" (Expand Search)
основеіііііе\\" » основіііііе\\" (Expand Search), основеііііе\\" (Expand Search), основніііііе\\" (Expand Search), основіеіііііе\\" (Expand Search), основееіііііе\\" (Expand Search)
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (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 ((основніе\\" OR основеіііііе\\\") OR основеі\\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основніе OR основеіііііе\ ) OR основеі\ )) OR (\ ґрунтова основ\ ))~.
