In the ever-expanding realm of contemporary systems, where data storage is more abundant and cost-effective, our data repositories grow rapidly. From basic text files to content-rich multimedia documents, we accumulate a diverse range of data. The challenge arises when the need to search for specific data, words, or phrases—whether through a direct search or related terms—calls for thoughtful consideration and the right tools.

Among the tools available today, Elasticsearch stands out as a mature search engine, residing at the core of the Elastic Stack. With a robust foundation and widespread adoption across various fields, Elasticsearch has proven itself as a reliable and versatile solution. This blog post kicks off by explaining the fundamentals and concepts of Elasticsearch, shedding light on its workings. Later, it offers a practical, easily understandable implementation guide that addresses various aspects of text search and analytics. We’ll delve into working with Elasticsearch in .Net Core 8, using the new Elasticsearch C# client (version 8.0+), covering indexing, searching, and ultimately aggregating data.

Whether you’re new to navigating the world of Elasticsearch or a seasoned explorer aiming to deepen your understanding, I hope this two-part guide help get you up to speed easily in working in ElasticSearch for full text search and analysis in .net core.
