      DATA CATALOG-SPECIFIC NOTE:

 ***************
 The fields in this file must match the fields in your Data Catalog's JSON API output.
 When you add a new metadata element (Symfony "entity") to your Data Catalog, 
 if you want it to be searchable, you must:
 1) add it to the Data Catalog's JSON output
 2) add a new <field> entry in this document to accept this metadata element
 3) add a new <copyField> directive to copy your new field into the "text" field.
 The "text" field is a catch-all field, into which other fields are copied.
 It is the ONLY field that is searched on by default. 
 It is defined after all our custom fields, just before the <dynamicField>'s (near line 475).
 If you want your new field to be searchable by default, you MUST copy it into the "text" field.

    <!-- Dynamic field definitions.  If a field name is not found, dynamicFields

         EXAMPLE:  name="*_i" will match any field ending in _i (like myid_i, z_i)
