Perhaps you should try some spelling variations:
основіные\\" » основные\\" (Expand Search), основііные\\" (Expand Search), основеіные\\" (Expand Search)
основеіеінііные\" » основіеінііные\" (Expand Search), основееінііные\" (Expand Search), основніеінііные\" (Expand Search), основіеіеінііные\" (Expand Search), основееіеінііные\" (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 основеіеінііные\\") OR основеі\\\")) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіные\ OR основеіеінііные ) OR основеі\ )) OR (\ ґрунтова основ\ )).
