In scan, the term is the query. For facets, the facet term has to be combined
with the previous query and that can be tricky.

Now I don't want to open up a whole nother can of worms. But doesn't this argue for yet one more element . a query. If you return the term "20101017 20101023" is the client likely to be able to formulate a valid query
without any help? We do it for facets, return a query with each facet term.

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".

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".
