What open source search library is used by Atlas Search?

Atlas Full-Text Search is built on Apache Lucene.


Thanks @Michael, that’s a great reference with some helpful technical details:

Lucene is built on the concept of inverted indexes, meaning that mapping a term to the document and field it appears in is super fast — much faster than in a traditional database. Combined with built-in query operators, default score ranking and traditional MongoDB-native functionality means that with Atlas Full-Text Search you get the flexibility of MongoDB combined with the speed of Lucene.

I :heart: this callout:

MongoDB + Lucene = :mag::green_heart:
