📄️ 📘 Why Atlas Search
Atlas Search is the built-in search solution for MongoDB Atlas. It is a fully managed service that is easy to set up, operate, and scale. Atlas Search is based on Apache Lucene and supports the Apache Lucene Query Parser Syntax. It supports text search, geospatial search, and faceted search.
📄️ 📘 How Atlas Search Works
Atlas Search uses inverted indexes to support text search queries. An inverted index is a data structure that maps each unique term in a collection to the documents that contain that term. The index is sorted by term, with each term referencing the documents that contain it.
