What is Elasticsearch?
A search engine that can quickly search and analyse large volumes of data.
Why It Matters
Elasticsearch powers fast, relevant search features across large datasets with support for filtering and faceting.
Real-World Example
An e-commerce site using Elasticsearch to let users search products with instant suggestions and filters.
“Understanding terms like Elasticsearch matters because it helps you have better conversations with developers and make smarter decisions about your software. You do not need to be technical. You just need to know enough to ask the right questions.”
