Perhaps you should try some spelling variations:
основееі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіееі\\" (Expand Search), основеееі\\" (Expand Search)
основеііііііееі\" » основііііііееі\" (Expand Search), основеіііііееі\" (Expand Search), основнііііііееі\" (Expand Search), основіеііііііееі\" (Expand Search), основееііііііееі\" (Expand Search)
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (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 основеііііііееі\\") OR основеі\\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основееі\ OR основеііііііееі ) OR основеі\ )) OR (\ ґрунтова основ\ ))~.
