Your're making many assumptions about how Solr works internally. One example of many: Solr streams documents (requests the stored fields right before they are written to the response stream) to support returning any number of documents. If you highlight documents, the stored fields need to be retrieved first. When streaming those same documents later, Solr will retrieve the stored fields again - reying on the fact that they should be cached by the document cache since they were just used. There are tons of examples of how things are architected to take advantage of the caches - it pretty much never makes sense to outright disable them. If they take up too much memory, then just reduce the size. -Yonik lucidimagination.com
