The use case is: 1. A SolrJ client updates the main index (and replicas) and issues a commit at regular intervals. 2. Another component updates the external files at other intervals.
Usually, the commits result in a new searcher which triggers the org.apache.solr.schema.ExternalFileFieldReloader, but only if there were changes to the main index. Using ReloadCacheRequestHandler in (2) above would result in the loss of index/replica synchronization provided by the commit in (1), and reloading the core is slow and overkill. I think it would be easier to have the SolrJ client in (1) always update a dummy document during each commit interval to force a new searcher.
