MongoSearcher - preserve indexes on truncate #406

Closed codespill closed 3 years ago

codespill commented 3 years ago

Description

When truncating MongoDB, collections are dropped, therefore all indexes are lost. This pull request propose using remove() method instead of drop(), which will remove all documents whilst preserving indexes.

Additional info

Documentation on remove() method:

To delete all documents in a collection, pass an empty document ({}).
