I haven't used lumify in a while, but you used to be able to just drag documents into the lumify UI in the browser and they would be able to go through the ingestion pipeline.
That being said, the project hasn't been committed to for a couple of months (and granted I haven't looked at it in a while) so I am not sure what state it is in. A project based on lumify that is more actively contributed to is visallo at
https://github.com/v5analytics/visallo.
Hope that helps! Email me or post to the google group if you need anything else. I would be more than happy to walk you through how to ingest any data you wish.
