I have a complex field that contains 3 sub fields, and it is multi-valued. I would like to be able to search on one of the sub fields, although if the search looked in all 3 that would be fine as well. In studio, I've created a content view although the advanced search section has the same results. Under the search layout section, if I select my schema on the right the complex multi-valued field does not show. I can choose More Widgets and add my own complex field, but when I do so I get a validation error:

On search layout, widget '

If I ignore the validation and bring this into Nuxeo, searching results in a general error.

Anyone have luck or any tips on searching a mutivalued complex field?
