This is a comprehensive reference for MongoDB operations, covering everything from basic CRUD to complex aggregation pipelines and index strategies. You get practical examples for document queries, array operators, text search, and multi-stage aggregations with $lookup and $facet. The indexing section walks through compound, partial, TTL, and geospatial indexes with actual createIndex calls. It's built for MongoDB 7.0+ and includes mongosh access for running commands directly. The code examples are production-ready patterns, not toy demos. If you're building or optimizing Mongo applications and want expert-level guidance on aggregations or performance tuning at your fingertips, this delivers.
