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