Newly created filter is not working in sidebar facet

[Raja muthukrishnan Ramanujam]

Hello Team,

I want to add "level"->[dc.feyenoord.level] as sidebar facet and search filter. I did all things like -> Add the following code snippet to "discovery.xml"->

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

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

        <property name="metadataFields">

            <list>

                <value>dc.feyenoord.level</value>

            </list>

        </property>

        <property name="facetLimit" value="5"/>

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

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

    </bean>

<property name="sidebarFacets">

            <list>

                <ref bean="searchFilterAuthor" />

                <ref bean="searchFilterSubject" />

                <ref bean="searchFilterIssued" />

                <ref bean="searchFilterContentInOriginalBundle"/>

                <ref bean="searchFilterEntityType"/>

                <ref bean="searchFilterlevel" />

            </list>

        </property>

        <!-- Set TagCloud configuration per discovery configuration -->

        <property name="tagCloudFacetConfiguration" ref="defaultTagCloudFacetConfiguration"/>

        <!--The search filters which can be used on the discovery search page-->

        <property name="searchFilters">

            <list>

                <ref bean="searchFilterTitle" />

                <ref bean="searchFilterAuthor" />

                <ref bean="searchFilterSubject" />

                <ref bean="searchFilterIssued" />

                <ref bean="searchFilterContentInOriginalBundle"/>

                <ref bean="searchFilterFileNameInOriginalBundle" />

                <ref bean="searchFilterFileDescriptionInOriginalBundle" />

                <ref bean="searchFilterEntityType"/>

                <ref bean="searchFilterIsAuthorOfPublicationRelation"/>

                <ref bean="searchFilterIsProjectOfPublicationRelation"/>

                <ref bean="searchFilterIsOrgUnitOfPublicationRelation"/>

                <ref bean="searchFilterIsPublicationOfJournalIssueRelation"/>

                <ref bean="searchFilterIsJournalOfPublicationRelation"/>

               <!--  <ref bean="searchFilterCustomMetadata" /> -->

               <ref bean="searchFilterlevel" />

            </list>

        </property>

<!--Use site to override the default configuration for the home page & default discovery page-->
                <entry key="site" value-ref="homepageConfiguration" />

and also add the line in '[dspace-install]/config/dspace.cfg' file

webui.browse.index.5 = level:metadata:dc.feyenoord.level.*:text

C:\dspace\bin>dspace index-discovery -b
