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