As far as I know, the ElasticSearch plugin does not support index mirroring for multiple datastore at once, it will only work for the one specified in the "elasticSearch.datastoreImpl" configuration, you should probably submit an feature request on the github project :
https://github.com/noamt/elasticsearch-grails-pluginMaybe you could try to manually declare another listener for hibernate, but I'm not sure this is going to be that simple. But if you want to try, in your grails-app/conf/spring/resources.groovy, declare a new
org.grails.plugins.elasticsearch.AuditEventListener for hibernate (considering you've kept "mongoDatastore" for the ES configuration):
auditListenerHibernate(AuditEventListener, ref("hibernateDatastore")) {
elasticSearchContextHolder = ref('elasticSearchContextHolder')
indexRequestQueue = ref('indexRequestQueue')
}
Just out of curiosity, what kind of errors does it give you when you make a hibernate domain searchable? Is it failing on startup or when you try to index it?
