dc.date.accessioned_dt is missing

[euler]

Dear All,

We recently migrated to a new server and I upgraded the version from 5.5 to 5.10 and then to 6.3. Before I moved it to the new server, I tested the migration first in my local instance. Previously, I posted this query last 2018 in which I asked about SOLR query for submitted items: https://groups.google.com/d/msg/dspace-tech/TCQlqVNOYcg/myxLBO3vCgAJ. I am flabbergasted to find out that after upgrading to the latest stable version, I am still having the same issue. I am really wondering why is it that there are no dc.date.accessioned_dt in the solr search core of our production server while in my local instance it is there? I stop tomcat, deleted the [dspace]/solr/search/data directory and run index-discovery -b but still no dc.date.accessioned_dt. I also run index-discovery -bf with the same results. I also deleted the conf directory and replaced it with a copy from my local instance but still no dc.date.accessioned_dt field. What could be the cause of this discrepancy when my local instance is [almost] a replica of our production server but our production server don't have dc.date.accessioned_dt?

Please help on how to resolve this because I really needed the dc.date.accessioned_dt metadata for submitted items SOLR query.

Thanks in advance!

Hi Euler,

I'd recommend checking your DSpace logs closely for errors while running a full reindex.  It's possible that an error is causing the dc.date.accessioned field to not be indexed properly.

You also should double check that your discovery.xml is the same on both sites.  That file configures which fields are indexed as *dates* (instead of strings) to support various searches/facets.  So, for example, the Recent Submission configuration area is one that specifies that it needs the 'dc.date.accessioned' field to be indexed _as a date_: https://github.com/DSpace/DSpace/blob/dspace-6_x/dspace/config/spring/api/discovery.xml#L249-L253

If you've modified the default configurations in discovery.xml this can affect what fields will be indexed.  Additionally, if errors occur during indexing, fields are often just skipped over entirely.  So, that's why it's important to look in the logs during indexing if you are finding issues with specific fields.

Good luck and hopefully that gives you a few clues of what to possibly look for.

Tim

Hi Tim,

Wow! The moment I read that specific line in discovery.xml that you mentioned, I knew right away what caused the dc.date.accessioned_dt field to be missing in my solr search core. I modified that line from dc.date.accessioned into dc.date.issued so that it will prevent the newly submitted OLD publications from displaying in the 'Recently Added' block on the home page and in the 'Recent Submissions' on the community and collection home page. The reason for this is that we want to highlight the new publications. I didn't realize that this will be the side effect. I guess I will have to look for other ways to suppress showing old publications that were recently submitted.

Thank you so much for this!

Euler
