DataImportHandler (DIH) is an add-on to Solr. It lets you import documents from a number of sources in a flexible way. The only connection DIH has to Lucene is that Solr uses Lucene as the index engine.
When you work with Solr you naturally talk about Solr Documents, if you were working with Lucene natively (without Solr) you would talk about Lucene documents, but they are basically the same thing. Are you having a specific issue? Or are you just trying to learn more about the technology? If you are mostly trying to understand DIH, then you should think in terms of Solr and Solr documents. Understand that Lucene is working behind the scenes, but you really don't need to worry about that all that often. -- View this message in context: http://lucene.472066.n3.nabble.com/Solr-Doc-Lucene-Doc-tp995922p996425.html Sent from the Solr - User mailing list archive at Nabble.com.
