The facet.prefix parameter limits the terms on which to facet to those
*starting with the given string prefix*.

It appears that you are looking to find it based on sequence of characters
appears in the middle of the string, this goes against the *facet.prefix*
definition.

Have you considered copying the /my_facet_field/(string field) into
/my_search_field/ (text field; analyzed to suit your search needs); With
that approach you can search in /my_search_field/ and facet on
/my_facet_field/
