The has nothing to do with
client-defined range facets. The client has the option to specify what
facets get returned and the server gets to decide what ranges are returned to
the client. None of that has changed.
The issue is the value that gets
returned in the server-defined range. Ed has advocated for the
<actualValue> returned to be a magic string such as “Last Week”.
I suggest that a more useful value for developer educational purposes would be “20101017
20101023” as it would show the developer how to use ranges in other
queries. It demonstrates that you have a date index that can be used for
range searches and you give an example of such a range search in your facet
response. This gets away from server “magic” and teaches the
developer something about your server’s capabilities.

We
*don't* have client-defined range facets, therefore the developer cannot figure
out how to create such a query anyway. Your argument does not hold true for
server-defined facets. To put it another way: there will be no sending of
strings that have not been sent first by the *server*, and therefore there will
be no "url hacking" or "query hacking".

Onderwerp: [search-ws-comment] "Last Week" is a bad idea for
<actualValue>
I’ve been giving more thought to our facets
conversation and have decided that I don’t like “Last Week”
as a term to be sent back to the server. I’m not saying it is
illegal or that the standard won’t support it. I’m just saying
I think it is a bad idea.
The reason is that it depends on server magic. The
client, or more importantly the developer, won’t learn anything about how
to construct other range queries if we hide how it is done behind magic
strings. If, instead, we send “20101017 20101023” as the
<actualTerm>, then the developer might be able to figure out how to
create their own query for “Two Weeks Ago”.
Of course, an <actualTerm> of “20101017
20101023” would want a <displayTerm> of “Last Week”.
