Perhaps you should try some spelling variations:
основіеные\\" » основные\\" (Expand Search), основііеные\\" (Expand Search), основеіеные\\" (Expand Search)
основеіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеіе\\" (Expand Search), основееіе\\" (Expand Search)
основеіеніа\\" » основініа\\" (Expand Search), основеніа\\" (Expand Search), основнініа\\" (Expand Search), основіеіеніа\\" (Expand Search), основееіеніа\\" (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 ((основіеные\\\" OR основеіе\\\") OR основеіеніа\\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіеные\ OR основеіе\ ) OR основеіеніа\ )) OR (\ ґрунтова основ\ )).
