Interesting! That is a very pertinent point that I had forgotten about
during this conversation.

Now that you have jogged my memory, I did create an enhancement request
for TB a long time ago to provide real server side search support. It
does have it, but since there is no way in TB to not download all of the
headers, there is no way to test it in that scenario.

I think I will go create the enhancement request for limiting how much
is downloaded, and link it to my server-side search support request, and
see what the response is.

Thanks for thinking this through with me... :)
