The former will sort result in ascending order of creation, and so will the latter. ```dart List queried = await MyService.index({r"query": where.id(Finder(filter: Filter(...)))); ``` Of course, you can use `package:sembast` queries. Just pass it as `query` within `params`. See the tests for more usage examples.
