2020 Releases¶

Atlas Search no longer requires downtime when rebuilding modified index definitions.

Added a new index option to exclude the norms field, allowing a search index to ignore field length when scoring search results.
Added the tokenOrder option to the autocomplete operator, supporting unordered terms in search queries.
Improved error messages to facilitate query debugging, including eliminating stack traces and other Java-specific messages.

Added support for geospatial queries, including:
- A new geo data type for indexing geographic point and shape coordinates.
- Two new operators, geoWithin and geoShape, to support queries on geospatial data, such as points and polygons.
Added autocomplete features to support better search-as-you-type functionality, including:
- A new autocomplete operator and index type.
- Analyzer-agnostic diacritic folding of field values.
- Scoring options, such as boost and constant.
- Compound queries that combine autocomplete with other $search operators.
- n-grams/shingles and edge n-grams from analyzed text.
