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