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