Conditional in the discovery.xml file

[jvl.vil...@gmail.com]

Is it possible to indicate a conditional when defining an index in the discovery.xml file?

I mean:

In the "list" section under "<value> dc.contributor.author </value>" I want to add the index of the "dc.coverage.temporal" field only if the content of the "dcterms.conformsTo" field is equal to the word "trademark"

    <bean id="searchFilterAuthor" class="org.dspace.discovery.configuration.DiscoverySearchFilterFacet">

        <property name="indexFieldName" value="author"/>

        <property name="metadataFields">

            <list>

                <value>dc.contributor.author</value>

<!-------------------------------            -->

<!-- HERE ADD NEW INDEX  -->

<!-------------------------------            -->

            </list>

        </property>

        <property name="facetLimit" value="10"/>

        <property name="sortOrderSidebar" value="COUNT"/>

        <property name="sortOrderFilterPage" value="COUNT"/>

    </bean>

thanks a lot
