No, don't do it like this.

Instead, look at Products/ATContentTypes/content/document.py: in its 
text field definition it has searchable=True.  Add that to the field 
definition in your custom schema and it should work: undo your changes 
to the catalog and reindex the SearchableText index and you should be 
able to find your content now.

See also the definition of SearchableText in 
Products/Archetypes/BaseObject.py
