Perhaps you should try some spelling variations:
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (Expand Search)
основеіеіііе\" » основіеіііе\" (Expand Search), основееіііе\" (Expand Search), основніеіііе\" (Expand Search), основіеіеіііе\" (Expand Search), основееіеіііе\" (Expand Search)
основені\" » основні\" (Expand Search), основі\" (Expand Search), основе\" (Expand Search), основіені\" (Expand Search), основеені\" (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 ((основеі\\\" OR основені\\") OR основеіеіііе\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основеі\ OR основені ) OR основеіеіііе )) OR (\ ґрунтова основ\ )).
