I am looking to specify an age range for the People search using the age slider. I am providing the default JSON string. Does anyone know how I can edit the end of the string to alter the age range (for example: 37-67)?

a:3:{s:6:"module";s:10:"bx_persons";s:6:"method";s:18:"get_search_options";s:6:"params";a:3:{i:0;s:8:"birthday";i:1;s:10:"datepicker";i:2;s:16:"datepicker_range";}}
