Description
With this course you will gain an in depth understanding of how a search engine works and how to implement it using Elasticsearch (or it's fork: OpenSearch). Not only will you learn the theory behind search and analytics, but we will also go through, step by step, how to concretely implement these concepts in ElasticSearch.We will explore many topics around search and you will learn to setup your own search engine with advanced capabilities such as full text search, live auto-completion, content recommendation, geo-spatial data querying.From a practical perspective we willroperly setting up our analyzersimplement different forms of data extraction and indexing into Elasticexplore Elastic's numerous querying capabilities, including full text searchexplore Elastic's numerous analytics capabilities, in particular aggregationbuild a faceted search engine in Javaexplore Geo-Spatial queryingsee how to properly configure our search engine for scalabilityAfter this course, these topics will no longer be mysterious and you'll have the fundamental understanding allowing you to efficiently implement them. Furthermore, have this understanding will open the door to the world's not only of search, but also high volume data analytics, and artificial intelligence, as they share common mathematical backgrounds.This course is not just about learning a technology, Elasticsearch, but also about building a strong background to use it properly.
