About This Book

• Learn about distributed indexing and real-time optimization to change index data on fly
• Index data from various sources and web crawlers using built-in analyzers and tokenizers
• This step-by-step guide is packed with real-life examples on indexing data

Who This Book Is For

This book is for developers who want to increase their experience of indexing in Solr by learning about the various index handlers, analyzers, and methods available in Solr. Beginner level Solr development skills are expected.

What You Will Learn

• Get to know the basic features of Solr indexing and the analyzers/tokenizers available
• Index XML/JSON data in Solr using the HTTP Post tool and cURL command
• Work with Data Import Handler to index data from a database
• Use Apache Tika with Solr to index word documents, PDFs, and much more
• Utilize Apache Nutch and Solr integration to index crawled data from web pages
• Update indexes in real-time data feeds
• Discover techniques to index multilanguage and distributed data in Solr
• Combine the various indexing techniques into a real-life working example of an online shopping web application

In Detail

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.

This fast-paced guide starts by helping you set up Solr. You'll quickly move on to indexing text and boosting the indexing time. Next, you'll focus on basic techniques for indexing a structured data source through Data Import Handler.

Moving on, you will learn techniques to perform real-time indexing and atomic updates. 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.

An OpenStack cloud is a complex jungle of components that can speed up managing a virtualization platform. Applications that are built for this platform are resilient to failure and convenient to scale. OpenStack allows administrators and developers to consolidate and control pools of compute, networking, and storage resources, with a centralized dashboard and administration panel to enable the large-scale development of cloud services. Begin by exploring and unravelling the internal architecture of the OpenStack cloud components. After installing the RDO distribution, you will be guided through each component via hands-on exercises, learning more about monitoring and troubleshooting the cluster. By the end of the book, you'll have the confidence to install, configure, and administer an OpenStack cloud. If you need to get started with OpenStack or want to learn more, then this book is your perfect companion. If you're comfortable with the Linux command line, you'll gain confidence in using OpenStack.
