: If you implement SolrCoreAware interface in your custom : UpdateRequestProcessorFactory, you could then access your cache via Solr : Core in the inform method, I think. Haven't tried it myself, but it looks : logical to me to start from there.
right ... but you really only need to be SolrCoreAware if you have to access the SolrCore during "initialization" You can also access the SolrCore from the SolrQueryRequest -- which is probably all you need for your UpdateRequestProcessorFactory. -Hoss
