[Dspace-tech] DiscoverySortFieldConfiguration not properly working

[RENATO CAMARGOS DE ALMEIDA SOUSA]

Hi,

DSpace v7.6,

I'm new to this area and would appreciate some help with an issue I'm facing.

I created a DiscoverySortFieldConfiguration in my Discovery.xml and added it to a DiscoveryConfiguration area. I was able to see the option correctly, and everything looked fine. The problem arose when I checked the item order; it wasn't sorting as I intended. Here's the bean:


<bean id="sortAvailable_Recentes" class="org.dspace.discovery.configuration.DiscoverySortFieldConfiguration">
    <property name="metadataField" value="dc.date.available"/>
    <property name="type" value="date"/>
    <property name="defaultSortOrder" value="desc"/>
</bean>


It's likely that there's a problem with the "date" type.

Could someone help me or provide a link with specific guidance regarding this issue?

Regards,
Renato Camargos

Hello, 

     I happened to encounter a similar issue before. In SOLR, this field is treated as text. You can go to the SOLR interface and find the following error message.
"sort":"dc.date.available desc",  ...  "error":{

"metadata":[ "error-class","org.apache.solr.common.SolrException", "root-error-class","org.apache.solr.common.SolrException"], "msg":"can not sort on multivalued field: dc.date.available of type: text", 

"code":400   

I used dc.date.accessioned instead.

Regards,

Caroline C.

Thanks for your message, Caroline.

I managed to solve the issue. I had created two customized beans of "DiscoveryConfiguration" and forgot to add my new "DiscoverySortFieldConfiguration" to one of them.

After adjusting this on "discovery.xml" and reindexing my items, the new "dc.date.available_dt" index (focus on the "_dt" suffix) was created on Solr. Consequently, everything worked as expected.
