city = [California], first_name = [Olivia],

_version_ = 1547262806014820352}, SolrDocument { id = 002, phone = [+148022338], 
city = [Hawaii], first_name = [Emma],

_version_ = 1547262806026354688}, SolrDocument { id = 003, phone = [+148022339], 
city = [Florida], first_name = [Sophia],

_version_ = 1547262806029500416}]} SolrDocument {id = 004, phone = [+148022337], city = [Texas], first_name = [Emily], 

_version_ = 1547262806014820352}, SolrDocument { id = 002, phone = [+148022338], 
city = [Hawaii], first_name = [Emma],

_version_ = 1547262806026354688}, SolrDocument { id = 003, phone = [+148022339], 
city = [Florida], first_name = [Sophia],

_version_ = 1547262806029500416}
