In Constellation, Advanced Search is not a separate option in the Data Reference Display as list, so it will not show there. To get Advanced Search, configure the Data Reference to open a results table and make the underlying list Data Page queryable. Update the list Data Page so it supports server-side filtering/search (for example, enable querying for the data source and expose searchable fields). Then set Display as to Table (or Autocomplete that opens the table picker) and submit the view. At runtime, the picker dialog will automatically show the Advanced Search/filter experience because the Data Page can be queried.
