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