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)
основеіеіеіеіеа\" » основіеіеіеіеа\" (Expand Search), основееіеіеіеа\" (Expand Search), основніеіеіеіеа\" (Expand Search), основіеіеіеіеіеа\" (Expand Search), основееіеіеіеіеа\" (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 основеіеіеіеіеа\\"))) OR (\\\"ґрунтова основ\\\"))\\"\"".
• Removing quotes may allow a broader search: ((\ ґрунтова (основеа\ OR (основеі\ OR основеіеіеіеіеа ))) OR (\ ґрунтова основ\ )).
