geoNear and $vectorSearch not yet supported

[lukehutch]

I need to be able to query geo points using $geoNear (with a 2dsphere index), and vector data using $vectorSearch. These don't seem to be supported yet in mongo_dart. Is there a way to perform these search types manually, or would support for these have to be added to mongo_dart?

$geoNear:

• https://www.mongodb.com/docs/manual/reference/operator/aggregation/geoNear/
• DocumentDB version: https://docs.aws.amazon.com/documentdb/latest/developerguide/geospatial.html

$vectorSearch:

• https://www.mongodb.com/products/platform/atlas-vector-search
• DocumentDB version: https://docs.aws.amazon.com/documentdb/latest/developerguide/vector-search.html

Hi $geoNear is supported (GeoNear class), vector search it is not.
I have also found a slightly different syntax with respect tot the amazon one: https://www.mongodb.com/docs/atlas/atlas-vector-search/vector-search-stage/
Atlas specific stages and operator will not be managed in mongo_dart_query. I will provide these operators and stages in the newcoming mongo_db_query, that aims to substite the former.
But still it will take some time to be ready.

Correct, the DocumentDB and MomgoDB syntaxes are slightly different... Maybe Amazon added vector search first, then Mongo went with a different syntax. I would assume the syntax will converge over time?

I really don't know ...

Hi, I have released in alpha version a new package for helping the creation of the query and update documents. The name of the package is mongo_db_query.
I have also published a development version of a new driver mongo_db_driver that has support for transactions. If you have time to test it would be a great help!

@giorgiofran thanks, this is super awesome, and thanks for letting me know. However, I pivoted away from using Mongodb because I switched to using Serverpod for the backend, and Serverpod uses Postgres for its ORM.
