Clarify time searching?

[rorlic]

The TREE specification says:

Same as the previous example but with the predicate tree:timeQuery expecting an xsd:dateTime.

This part is clear to me: when filling in the search form, the hydra variable should be provided as a xsd:dateTime literal value and will result in a URL that can be requested.

This time however, when the page itself does not exist, a redirect is doing to happen to the page containing the timestamp. A tree:path can indicate the time predicate which is intended.

I assume there is a typo and should read:

a redirect is going to happen

If a page exists at this URL, the server returns it. That part is clear.
If no page exists at this URL, a redirect happens to the page containing the timestamp. This part is unclear to me.

I understand that because the server offers this search form it knows what predicate path (should it be property path?) to use for comparison. But, what does it compare against? I assume members as it says:

can indicate the time predicate which is intended

What happens if no member matches the given value? A not-found (404) HTTP result?
What happens if multiple members match that value in different pages?

Maybe we can clarify this in the TREE specification?

In addition: if it is a property path instead of a predicate path then the result of applying this property path can be multiple values. Does a member match if ANY of these values match the given timestamp?
