Perhaps you should try some spelling variations:
основеіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеіе\\" (Expand Search), основееіе\\" (Expand Search)
основеіееіе\" » основіеіе\" (Expand Search), основееіе\" (Expand Search), основніеіе\" (Expand Search), основіеіееіе\" (Expand Search), основееіееіе\" (Expand Search)
основнііе\" » основні\" (Expand Search), основные\" (Expand Search), основінііе\" (Expand Search), основенііе\" (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 ((основеіе\\\" OR основнііе\\") OR основеіееіе\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основеіе\ OR основнііе ) OR основеіееіе )) OR (\ ґрунтова основ\ )).
