Perhaps you should try some spelling variations:
основееі\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіееі\" (Expand Search), основеееі\" (Expand Search)
основееііа\\" » основііа\\" (Expand Search), основеіа\\" (Expand Search), основнііа\\" (Expand Search), основіееііа\\" (Expand Search), основеееііа\\" (Expand Search)
основіні\\" » основні\\" (Expand Search), основі\\" (Expand Search), основііні\\" (Expand Search), основеіні\\" (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 основееііа\\\") OR основіні\\\")) OR (\\\"ґрунтова основ\\\"))~\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основееі OR основееііа\ ) OR основіні\ )) OR (\ ґрунтова основ\ ))~.
