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