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