If there are multiple instances of a parameter which can only
meaningfully have one value, then it's essentially arbitrary which
value is used.  And collapsing on multiple values at the same time isn't
supported.

Yes - this means that the previous search had a collapse on value 1.

We track such things so we know when to force the first page of search
results - if you're on page 6 and change the collapse setting, it
doesn't make much sense to stay on page 6.
