Perhaps you should try some spelling variations:
основіе\\" » основі\\" (Expand Search), основе\\" (Expand Search), основные\\" (Expand Search), основііе\\" (Expand Search), основеіе\\" (Expand Search)
основіені\\" » основіні\\" (Expand Search), основені\\" (Expand Search), основныені\\" (Expand Search), основні\\" (Expand Search), основііені\\" (Expand Search), основеіені\\" (Expand Search)
основныеіныееа\" » основіныеіныееа\" (Expand Search), основеныеіныееа\" (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 ((основіе\\\" OR основіені\\\") OR основныеіныееа\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіе\ OR основіені\ ) OR основныеіныееа )) OR (\ ґрунтова основ\ )).
