Apache Solr for Indexing Data

Overview of this book

Apache Solr is a widely used, open source enterprise search server that delivers powerful indexing and searching features. These features help fetch relevant information from various sources and documentation. Solr also combines with other open source tools such as Apache Tika and Apache Nutch to provide more powerful features. This fast-paced guide starts by helping you set up Solr and get acquainted with its basic building blocks, to give you a better understanding of Solr indexing. You’ll quickly move on to indexing text and boosting the indexing time. Next, you’ll focus on basic indexing techniques, various index handlers designed to modify documents, and indexing a structured data source through Data Import Handler. Moving on, you will learn techniques to perform real-time indexing and atomic updates, as well as more advanced indexing techniques such as de-duplication. Later on, we’ll help you set up a cluster of Solr servers that combine fault tolerance and high availability. You will also gain insights into working scenarios of different aspects of Solr and how to use Solr with e-commerce data. By the end of the book, you will be competent and confident working with indexing and will have a good knowledge base to efficiently program elements.

Content streaming


In Solr, we can index remote or local files by enabling remote streaming in solrconfig.xml. Let's see how we can use this feature in Solr, we'll follow the steps given here to enable the remote streaming feature.

Let's use our newly created languages-example core and modify solrconfig.xml. We'll replace the requestDispatcher config in our solrconfig.xml file with the following lines:

  <requestDispatcher handleSelect="false" > 
    <requestParsers enableRemoteStreaming="true" 
      multipartUploadLimitInKB="2048000"
      formdataUploadLimitInKB="2048"
      addHttpRequestToContext="false"/> 
  </requestDispatcher>

The enableRemoteStreaming="true" property will enable the remote streaming feature. This will enable us to index remote or local files. Let's go ahead and index a remote file in our Solr index:

$ curl http://localhost:8983/solr/languages-example/update?commit=true -F stream.url=https://raw.githubusercontent.com/sachin-handiekar/SolrIndexingBook...
