Perhaps you should try some spelling variations:
основіные\\" » основные\\" (Expand Search), основііные\\" (Expand Search), основеіные\\" (Expand Search)
основеіеіееіные\" » основіеіееіные\" (Expand Search), основееіееіные\" (Expand Search), основніеіееіные\" (Expand Search), основіеіеіееіные\" (Expand Search), основееіеіееіные\" (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 ((основіные\\\" OR основеіеіееіные\\") OR основеі\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіные\ OR основеіеіееіные ) OR основеі )) OR (\ ґрунтова основ\ )).
