Perhaps you should try some spelling variations:
основеіа\" » основі\" (Expand Search), основе\" (Expand Search), основні\" (Expand Search), основіа\" (Expand Search), основеа\" (Expand Search), основніа\" (Expand Search), основіеіа\" (Expand Search), основееіа\" (Expand Search)
основеі\\" » основі\\" (Expand Search), основе\\" (Expand Search), основні\\" (Expand Search), основіеі\\" (Expand Search), основееі\\" (Expand Search)
основіеііа\" » основііеііа\" (Expand Search), основеіеііа\" (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 ((основіеііа\\" OR основеіа\\") OR основеі\\\")) OR (\\\"ґрунтова основ\\\"))*\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова ((основіеііа OR основеіа ) OR основеі\ )) OR (\ ґрунтова основ\ ))*.
