<p>Hi Verena,</p>
<p>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. <br>
</p>
<p>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:</p>

<p class="MsoNormal">We received a request from one of our
researchers for the option to search exact DOIs. He
maintains some EPrints collections for research groups and
often gets sent only the DOI for the publication that he is
supposed to add to a collection.<o:p></o:p></p>
<p class="MsoNormal">I added the two eprints fields used in
our system for DOIs to the eprints_search_advanced.pl
script. The problem is that the search term, e.g.
10.1016/j.ejor.2018.02.047, is split into parts for the
search with several to many entries shown as results.
Additionally, the search ignores parts of the DOI (Ignoring:
"10", "j", "02").<o:p></o:p></p>
