• The words AND, OR and NOT may confuse the search; try adding quotes: "\"((\\"ґрунтова ((основіе\\" OR основеіе\\") OR (основеііе\\" OR основні\\"))) OR (\\"ґрунтова основ\\"))~\"".
• Removing quotes may allow a broader search: (( ґрунтова ((основіе OR основеіе ) OR (основеііе OR основні ))) OR ( ґрунтова основ ))~.
