Newswise — October 18, 2016 –Wolters Kluwer, a leading global provider of information and point of care solutions for the healthcare industry, announced today that Dion Olsthoorn, Senior Software Engineer, Wolters Kluwer Global Platform Office, shared with Lucene/Solr Revolution Conference 2016 attendees how virtualization, cloud elasticity and an innovative queuing system enabled millions of documents to be loaded and indexed in SolrCloud in a matter of hours. The inventive approach taken by the Wolters Kluwer technology team sets the stage for same-day access to huge volumes of new medical full text and bibliographic resources, as well as more powerful searching and higher relevance results. The technology initiative is part of a broader search platform that will enable the company to redefine the way its customers perform searches.
The Lucene/Solr Revolution Conference 2016, which took place October 11-14 in Boston, is the largest conference dedicated to Solr, an open source enterprise search platform built on Apache Lucene™ that powers the search and navigation features of many of the world's largest internet sites. Olsthoorn’s presentation, “Loading 350M Documents into a Large Solr Cluster in 8 Hours or Less,” demonstrated how a large set of Extensible Markup Language (XML) documents can be rapidly and efficiently loaded into SolrCloud, a cluster of Solr servers that combines fault tolerance and high availability.
“The challenge with high demand medical research is ensuring the continuous and significant volume of new content is made quickly and reliably available to end users, which requires loading and painstakingly indexing complex synonym-ladened terminology to highly accessible search engines,” said Olsthoorn. “Once complete, Solr searches are extremely fast and accurate.”
Faced with loading 350 million XML documents to SolrCloud, the Wolters Kluwer team set out to identify an approach that would allow them to complete the task faster (hours vs. days) to improve the overall search experience. Working with Solr ZooKeeper, they set up a series of virtual servers to manage the content upload. Once the project was complete, the servers were simply deleted. By eliminating the capital investment into physical servers, this approach lowered costs and provided on-demand access to extra processing power when it was needed.
“We are constantly seeking ways to leverage the latest technology advancements to improve upon the status quo to ensure that medical researchers and other medical professionals have immediate access to the most current, relevant and trusted clinical content,” said Sahil Gupta, Chief Technology Officer, Health Learning, Research & Practice, Wolters Kluwer. “This innovative approach to rapidly populating SolrCloud represents the future of medical content searches, benefiting the clinician end user and, ultimately, the patient. We are honored to have had this opportunity to share our expertise with other thought-leaders who share our interest in building and deploying Solr open source search technology.” ###
