Perhaps you should try some spelling variations:
основеа\\" » основе\\" (Expand Search), основіеа\\" (Expand Search), основееа\\" (Expand Search)
основеі\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіеі\" (Expand Search), основееі\" (Expand Search)
основеіеіііеііеа\\" » основіеіііеііеа\\" (Expand Search), основееіііеііеа\\" (Expand Search), основніеіііеііеа\\" (Expand Search), основіеіеіііеііеа\\" (Expand Search), основееіеіііеііеа\\" (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 (основеа\\\" OR (основеі\\" OR основеіеіііеііеа\\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основеа\ OR (основеі OR основеіеіііеііеа\ ))) OR (\ ґрунтова основ\ )).
