How to add configuration item to contextual search on the incident form?

[Steve Wilson2]

I am trying to add configuration item as part of the contextual search on an incident form. When I go to the table configuration in contextual search and add a search field I do not see configuration item.

seems like that's reference field , that's the reason.

Procedure

1. Navigate to Contextual Search > Table Configuration and open the record.
2. Click New in the Search Fields related list.
3. Select the field to use and the order for that field.
   Note: Only text fields can be selected.

I'm guessing it has to do with it being a reference field.  Maybe you can follow this docs article Create a filter configuration using script so you can return the display value.

That looks like the right path but it doesnt change my results.

I added query_table.addQuery('cmdb_ci', current.cmdb_ci); to the filter configuration but no additional articles are shown.

Both the incident and the knowledge article are pointing to the same CI in the cmdb_ci field.
