Although Solr allows us to use the partial update API to update a single field of our document, what it does in the background is the complete reindexing of a document. However, there are situations where such reindexing is not possible. For example, we can have an index containing articles about published books, and we can store the information on how many users visited this article and read it. The number of users is so high that we have thousands of updates per second. Sending a high amount of updates can be demanding for Solr; however, we can store such information in external files and use it for boosting or sorting. This recipe will show how to do this.

You're reading from Solr Cookbook - Third Edition
Rafał Kuć is a software engineer, trainer, speaker and consultant. He is working as a consultant and software engineer at Sematext Group Inc. where he concentrates on open source technologies such as Apache Lucene, Solr, and Elasticsearch. He has more than 14 years of experience in various software domains—from banking software to e–commerce products. He is mainly focused on Java; however, he is open to every tool and programming language that might help him to achieve his goals easily and quickly. Rafał is also one of the founders of the solr.pl site, where he tries to share his knowledge and help people solve their Solr and Lucene problems. He is also a speaker at various conferences around the world such as Lucene Eurocon, Berlin Buzzwords, ApacheCon, Lucene/Solr Revolution, Velocity, and DevOps Days. Rafał began his journey with Lucene in 2002; however, it wasn't love at first sight. When he came back to Lucene in late 2003, he revised his thoughts about the framework and saw the potential in search technologies. Then Solr came and that was it. He started working with Elasticsearch in the middle of 2010. At present, Lucene, Solr, Elasticsearch, and information retrieval are his main areas of interest. Rafał is also the author of the Solr Cookbook series, ElasticSearch Server and its second edition, and the first and second editions of Mastering ElasticSearch, all published by Packt Publishing.
