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