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