Perhaps you should try some spelling variations:
основеа\" » основе\" (Expand Search), основіеа\" (Expand Search), основееа\" (Expand Search)
основіе\" » основі\" (Expand Search), основе\" (Expand Search), основііе\" (Expand Search), основеіе\" (Expand Search)
основные\" » основе\" (Expand Search), основні\" (Expand Search), основіные\" (Expand Search), основеные\" (Expand Search)
основеееа\" » основіеееа\" (Expand Search), основееееа\" (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 ((основіе\\" OR основные\\") OR основеееа\\"))) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова (основеа OR ((основіе OR основные ) OR основеееа ))) OR ( ґрунтова основ ))~.
