"No community found" when trying to create a new community or collection

[Manuela Ferreira]

Hello!

I'm running DSpace 7.6 with a migrated database, apparently successfully, from DSpace 6.3.

However, when trying to create a new community or a new collection, the list of communities that could be parent appears empty with the message "No community found", as can be seen in the attachment, even though there are several communities in the database.

In the logs, there is only an informational message "2024-02-20 11:42:07,754 INFO 4843d4f6-7f1c-4ace-977f-a0293e88cab9 58ea537e-620e-4c52-a1b8-4d22e9fc82a6 org.dspace.app.rest.utils.DSpaceAPIRequestLoggingFilter @ Before request [GET /server/api/discover/search/objects] originated from /home".

I would like to know how to fix this issue.

Thank you for your attention to this matter.

Sincerely,
Manuela Klanovicz Ferreira

Hi,

More than likely either you have a frontend/backend error occurring, or you need to reindex (as your Solr index is outdated).

To look for errors, see the troubleshooting guide: https://wiki.lyrasis.org/display/DSPACE/Troubleshoot+an+error#Troubleshootanerror-DSpace7.x(orabove)

To reindex, you can run `./dspace index-discovery -b`

Hi!

I found the issue. To filter only items in the default discovery filter that appears when we perform an empty search in DSpace 7.6, I modified the defaultFilterQueries property in the defaultConfiguration in the file <dspace>/config/spring/api/discovery.xml, as shown below:

Before:

<!--The default configuration settings for discovery-->
    <bean id="defaultConfiguration" class="org.dspace.discovery.configuration.DiscoveryConfiguration" scope="prototype">

...

       <property name="defaultFilterQueries">
            <list>
                <!--Only find items, communities and collections-->
                <value>(search.resourcetype:Item AND latestVersion:true) OR search.resourcetype:Collection OR search.resourcetype:Community</value>
                <value>-withdrawn:true AND -discoverable:false</value>
            </list>
        </property>

...

After

<!--The default configuration settings for discovery-->
    <bean id="defaultConfiguration" class="org.dspace.discovery.configuration.DiscoveryConfiguration" scope="prototype">

...

       <property name="defaultFilterQueries">
            <list>
                <!--Only find items, communities and collections-->
<value>(search.resourcetype:Item AND latestVersion:true)</value>
                <value>-withdrawn:true AND -discoverable:false</value>
            </list>
        </property>

...

This affected the search for communities and collections when creating new subcommunity/collection or item, respectively.

I reverted the modification, and the 'No community found' issue was resolved. 

However, now I'm trying to find a way to return only items when performing an empty search in the search box of DSpace 7.6, meaning I don't want communities and collections to be returned in this search. 

Does anyone know how to achieve this?

Thank you
