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