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".
