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