Date facet not showing up on Search page

[Lauren Sorensen]

Example search page (after having entered the search from main page, clicked eyeglass icon. This page shows up with facets on the side, but no date facet is presented. https://virtualtribunals-stage.stanford.edu/nuremberg?search_field=all_fields&q=1936-1940

This is the expected behavior because the two documents in the result set do not have any values in the date facet (date_hierarchy_ssim).

There is no <unitdate> in the EAD for that document:

            <did>
              <unittitle>U.S. Document Book M: 1933 - 1936 Preparation for Aggression</unittitle>
              <unitid>H-1120</unitid>
              <physdesc altrender="whole">
                <extent altrender="materialtype spaceoccupied">1 item(s)</extent>
                <extent altrender="carrier">191 pages</extent>
                <physfacet>Folders</physfacet>
              </physdesc>
              <container id="aspace_e1e776c6b5e24bba082e9ff2883fe5de" label="Text" type="box">9</container>

            </did>
