    public class AlfrescoCoreAdminHandler
extends org.apache.solr.handler.admin.CoreAdminHandler
    Alfresco Solr administration endpoints provider. A customisation of the existing Solr CoreAdminHandler which offers additional administration endpoints. Since 1.5 the behaviour of these endpoints differs a bit depending on the target core. This because a lot of these endpoints rely on the information obtained from the trackers, and trackers (see SEARCH-1606) are disabled on slave cores. When a request arrives to this handler, the following are the possible scenarios:
    • a core is specified in the request: if the target core is a slave then a minimal response or an empty response with an informational message is returned. If instead the core is a master (or it is a standalone core) the service will return as much information as possible (as it happened before 1.5)
    • a core isn't specified in the request: the request is supposed to target all available cores. However, while looping, slave cores are filtered out. In case all cores are slave (i.e. we are running a "pure" slave node) the response will be empty, it will include an informational message in order to warn the requestor. Sometimes this informative behaviour is not feasible: in those cases an empty response will be returned.
