In this chapter, we saw how we can use the data import handler provided by Solr to import data from various datasources. There are a lot of things that we did not cover in this chapter, and they are beyond the scope of this book, such as entity processors, transformers, and many more. You can read more about this advanced feature on the Solr Data Import Handler wiki (https://wiki.apache.org/solr/DataImportHandler).

In the next chapter, we'll see how we can extract data from various file formats, such as .doc, .ppt, .xls, and many more, and index it in Solr using Apache Tika.
