Perhaps you should try some spelling variations:
основіе\" » основі\" (Expand Search), основе\" (Expand Search), основные\" (Expand Search), основііе\" (Expand Search), основеіе\" (Expand Search)
основіеееі\" » основіееі\" (Expand Search), основеееі\" (Expand Search), основныеееі\" (Expand Search), основііеееі\" (Expand Search), основеіеееі\" (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 ((основіе\\" OR основіеееі\\") OR основені\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіе OR основіеееі ) OR основені )) OR (\ ґрунтова основ\ ))~.
