OrgPublisher contains a couple of ways to search for users or specific data in a Published chart.
A Look For/quick search type option allows a quick character by character Search feature that can be used from the application or from a Published chart.
A Full Search option is also available. This option allows for searching by Name, Job Title, Box Title, All Fields (including any/all Custom Fields you made Searchable) or Groups may have in your Pluginx or EChart published charts.
If you have Succession Planning abilities, and have enabled it, the Search feature will include Successor(s) in a box and Person Succession count.
A chart published as HTML will use the List View to allow the user to locate an individual in the chart. The List View should be sorted alphabetically prior to publishing the chart. Other alternatives for HTML charts are available in the Software Developer's Kit available on this web site.
