Perhaps you should try some spelling variations:
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (Expand Search)
основеіііа\" » основіііа\" (Expand Search), основеііа\" (Expand Search), основніііа\" (Expand Search), основіеіііа\" (Expand Search), основееіііа\" (Expand Search)
основеіііеіеііа\" » основіііеіеііа\" (Expand Search), основеііеіеііа\" (Expand Search), основніііеіеііа\" (Expand Search), основіеіііеіеііа\" (Expand Search), основееіііеіеііа\" (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 (основеі\\\" OR (основеіііа\\" OR основеіііеіеііа\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основеі\ OR (основеіііа OR основеіііеіеііа ))) OR (\ ґрунтова основ\ )).
