I would like to dedicate my most sincerely appreciation to ElasticSearch, the main drive that made me started ANVERE. It all began in 2016, when I was tasked with building an autocomplete API for geographical data at Goong. The search engine that was employed at that time was based on SphinxSearch, took forever to return subpar results - underperforming in all aspects. This made me so frustrated that I decided to migrate to a completely new search engine instead of trying to fix it....
