Summary
In this chapter, we saw how Solr can be used to index multilanguage documents with some easy configuration, and also language detection, which can be used to automatically detect the language of a document. Plus, we covered the deduplication technique, which Solr supports natively. It can be used to overwrite/remove documents from Solr using the hashing/fingerprint technique. We also covered in brief content streaming and the integration of Apache UIMA with Solr.
In the next chapter, we'll cover how we can easily set up a cluster of Solr servers.
