[EP-tech] Change EPrint field type.



We have an EPrint field that we intended to use to hold ORCIDs originally defined as ‘type’ => ‘text’ and we have done so and thus we have data in the fields already. 


The problem is that an advanced search for an ORCID ID will return more than just the exact ORCID ID due to the fuzzy matching imposed on a ‘text’ field.  I was advised to change this to ‘type’ => ‘id’ to force the advanced search to use exact matching.


My question is how can I change this field to ‘type’ => ’id’ including any database changes if they are needed (we are using MySQL)?  Obviously we edit the eprint_fields.pl file and change the definition, but what if anything else needs to be done on the database backend to accommodate this change?


Any help would be appreciated.


Thanks in advance,
