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