Born to code, David Smiley is a software engineer that’s passionate about search, Lucene, spatial, and open-source. He has a great deal of expertise with Lucene and Solr, which started in 2008 at MITRE. In 2009 as the lead author, he wrote Solr 1.4 Enterprise Search Server, the first book on Solr, published by PACKT. It was updated in 2011, and again for this third edition. After the first book, he developed a one and two-day Solr training courses delivered a half dozen times within MITRE, and he delivered LucidWorks’ training once too. Most of his excitement and energy relating to Lucene is centered on Lucene’s spatial module to include Spatial4j, which he is largely responsible for. He presented his progress on this at Lucene Revolution and other conferences several times. Finally, he currently holds committer / Project Management Committee (PMC) status with the Lucene/Solr open-source project. During all this time, David has staked his career on search, working exclusively on such projects, formerly for MITRE, and now as an independent consultant for various clients.
