Implement listIndexes command stub that returns valid empty results in the same format as MongoDB.

Ignore cursor and comment fields.

Yes, indexes are not supported yet. That's tracked as #78.

Will it be updated later
My English is poor, thank you for understanding

[AlekSi]

Yes, we plan to add support for indexes and other features needed by typical applications that use pymongo and other MongoDB drivers.
No worries :)

Currently switching from mongodb to FerretDB
The problem can't be solved
When can you release a version

[AlekSi]

It might be a bit early to switch to FerretDB right now. We plan to add support for indexes in several months. Our roadmap is there: https://github.com/orgs/FerretDB/projects/2/views/1
