The page on [Time Filters](https://docs.datomic.com/cloud/time/filters.html) mentions in the intro:

> Datomic databases can be filtered with the time-based predicates `asOf` and `since` . **Or, you can bring your own predicate with `filter`.** In addition, you can get an unfiltered view of all history via `history`.

However the Client API does not have the `filter` function, and I presume Cloud does not support that?

It looks like this page might have been copied from On-Prem documentation and the section about `filter` further down removed, but the highlighted sentence was left in.

I think it would be clearer if it is also removed (it threw me off course for a while, thinking predicate filters are supported). The paragraph will then read like this:

> Datomic databases can be filtered with the time-based predicates `asOf` and `since`. In addition, you can get an unfiltered view of all history via `history`.

Thanks for catching that.  
I’ve removed the mention of predicate filters.
