How to sort a facet in DESC order?

[Diego Brice]

Hi.  Is it possible to sort facet values in DESC order?. I want to have the Date issued facet in descending order. I tried to add the line in red to the bean configuration but it is not valid:

    <bean id="searchFilterIssued" class="org.dspace.discovery.configuration.DiscoverySearchFilterFacet">
        <property name="indexFieldName" value="dateIssued"/>
        <property name="metadataFields">
            <list>
                <value>dc.date.issued</value>
            </list>
        </property>
        <property name="type" value="text"/>
        <property name="facetLimit" value="5"/>
        <property name="sortOrderSidebar" value="VALUE"/>
        <property name="sortOrderFilterPage" value="VALUE"/>
        <property name="isOpenByDefault" value="false"/>
        <property name="pageSize" value="10"/>
        <property name="exposeMinAndMaxValue" value="true"/>
<property name="defaultSortOrder" value="desc"/>
    </bean>

TIA

Hi Diego,

That setting you've added to org.dspace.discovery.configuration.DiscoverySearchFilterFacet is not valid because there is no "defaultSortOrder" property defined on that Java object https://github.com/DSpace/DSpace/blob/main/dspace-api/src/main/java/org/dspace/discovery/configuration/DiscoverySearchFilterFacet.java

In other words, in that Spring XML configuration, you can only specify properties which exist on the corresponding Java object.

At this time, I'm not aware of a way to configure a facet to support descending order by default.  That'd likely need to be done via custom Java code.
