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