In a blog post by Stuart Cam, the process of building a real-time address search system using the Australian Geocoded National Address File (G-NAF) and Elasticsearch is discussed. The G-NAF, an authoritative and comprehensive dataset containing nearly 14 million addresses, was made publicly available by PSMA Australia in 2016. The blog outlines how to leverage Elasticsearch's search_as_you_type feature to implement a typeahead search functionality, demonstrating step-by-step procedures such as downloading necessary tools, staging the G-NAF datasets into a SQL database, creating Elasticsearch indices and mappings, and conducting both address and geo-distance queries. The tutorial is framed within the context of the author's experience with Elastic's Spacetime program, which allows engineers to explore innovative projects, in this case utilizing the F# programming language.
