Faceting numeric and date ranges - Apache Solr 3 Enterprise Search Server [Book]
Born to code, David Smiley is a senior software engineer, book author, conference speaker, and instructor. David is the principal author of "Solr 1. David plays a lead technical role in a large-scale Solr project in which he has implemented geospatial search based on geohash prefixes, wildcard ngram query parsing, searching multiple multi-valued fields at coordinated positions, part-of-speech search using Lucene payloads, and other things.
He has contributed code to Lucene and Solr and is active in the open-source community.

He also used the competing Endeca commercial product, too, but hopes to never use it again. Fascinated by the 'craft' of software development, Eric Pugh has been heavily involved in the open source world as a developer, committer, and user for the past five years.
He is an emeritus member of the Apache Software Foundation and lately has been mulling over how we solve the problem of finding answers in datasets when we don't know the questions ahead of time to ask. In biotech, financial services, and defense IT, he has helped European and American companies develop coherent strategies for embracing open source search software.

As a speaker, he has advocated the advantages of Agile practices with a focus on testing in search engine implementation. The patch was subsequently cleaned up and enhanced by three other individuals, demonstrating the power of the open source model to build great code collaboratively.
