Perhaps you should try some spelling variations:
основееі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіееі\\" (Expand Search), основеееі\\" (Expand Search)
основееіеіные\" » основіеіные\" (Expand Search), основееіные\" (Expand Search), основніеіные\" (Expand Search), основіееіеіные\" (Expand Search), основеееіеіные\" (Expand Search)
основеные\\" » основные\\" (Expand Search), основіеные\\" (Expand Search), основееные\\" (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 (основеные\\\" OR основееіеіные\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основееі\ OR (основеные\ OR основееіеіные ))) OR (\ ґрунтова основ\ )).
