Perhaps you should try some spelling variations:
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (Expand Search)
основеііа\\" » основііа\\" (Expand Search), основеіа\\" (Expand Search), основнііа\\" (Expand Search), основіеііа\\" (Expand Search), основееііа\\" (Expand Search)
основеіеіееііа\" » основіеіееііа\" (Expand Search), основееіееііа\" (Expand Search), основніеіееііа\" (Expand Search), основіеіеіееііа\" (Expand Search), основееіеіееііа\" (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 (основеііа\\\" OR основеіеіееііа\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основеі\ OR (основеііа\ OR основеіеіееііа ))) OR (\ ґрунтова основ\ )).
