There is a DirectoryFactory in Solr that could be used to make Lucene's RAMDirectory. But then you'd have to reindex everything when restarting Solr. Doesn't seem to make much practical sense to use it, not even for performance reasons thanks to Lucene and Solr both caching what they need fast anyway.

if yes, how can I use it?

(do you think it fits even in acts_as_solr for Rails?)
