I am facing problem integrating Elastic Search with Mahout because in
ES am not able to control the format in which the files are indexed.
For example in Solr or Lucene, following links
says that you can add term vector and gives a command which would
create Mahout documents from search indices.
Say if I want to trigger an event, that whenever a record is added to
Elastic Search engine it also gets added to Mahout, Mahout actually
doesn't understand the indexed files. Is it possible to index the
records in ES in another format like csv, json, etc? Since ES has
emerged from Lucene, I believe there should be a way to do it.
I would really appreciate any information on this topic.
