I haven't used elastic search but I've used lucene/solr. It's similar to a technology our startup created which was acquired by IBM and is now part of the Watson portfolio. I think our indexing engine was faster. I know for sure we were better at getting data into the index than lucene appears to be. What are the common connector frameworks for lucene? Or do you generally just push the documents to the index?
