Perhaps you should try some spelling variations:
основееі\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіееі\" (Expand Search), основеееі\" (Expand Search)
основееіні\\" » основіні\\" (Expand Search), основені\\" (Expand Search), основніні\\" (Expand Search), основіееіні\\" (Expand Search), основеееіні\\" (Expand Search)
основііа\\" » основі\\" (Expand Search), основні\\" (Expand Search), основіііа\\" (Expand Search), основеііа\\" (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 ((основееі\\" OR основііа\\\") OR основееіні\\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основееі OR основііа\ ) OR основееіні\ )) OR (\ ґрунтова основ\ ))~.
