[EP-tech] Searching for DOIs

Hi Verena,

I think this is due to the id_number field for eprint being set as a 
'text' rather than an 'id' type field.? This can be fixed by editing the 
eprint_fields.pl file that you will likely already have in your 
archive's cfg/cfg.d/ directory and changing the type for the id_number.? 
If this file is not already in your archive's cfg/cfg.d/ directory it 
can be copied to this directory from EPrints' lib/cfg.d/ (EPrints 3.3) 
or flavours/pub_lib/cfg.d/ (EPrints 3.4).? Being an 'id' rather than 
'text' field does not effect the representation of this field in the 
database, so you can just reload the web server (e.g. apachectl 
graceful) to effect this change.

Making this change means you need to search for the exact DOI in a 
case-sensitive way.? Often the way that DOIs are entered for this field 
varies between users, so it may be necessary to tidy up the DOIs you 
already have entered for this field so that you can actually search for 
DOIs in the form:
