Perhaps you should try some spelling variations:
основееі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіееі\\" (Expand Search), основеееі\\" (Expand Search)
основееііні\" » основііні\" (Expand Search), основеіні\" (Expand Search), основнііні\" (Expand Search), основіееііні\" (Expand Search), основеееііні\" (Expand Search)
основіні\\" » основні\\" (Expand Search), основі\\" (Expand Search), основііні\\" (Expand Search), основеіні\\" (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 (основіні\\\" OR основееііні\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основееі\ OR (основіні\ OR основееііні ))) OR (\ ґрунтова основ\ )).
