Looking at the major 'discovery' products, Summon, Primo, EDS....

...all three will provide some results to un-authenticated users (the 
general public), but have some portions of the corpus that are 
restricted and won't show up in your results unless you have an 
authenticated user affiliated with customer's organization.

So when we look around on the web for Summon and Primo examples, we can 
for instance do some sample searches there even without logging in or 
being affiliated with the particular institution.

But we are only seeing a subset of results there, not actually seeing 
everything, since we didn't auth.

But most of these examples I look at don't, in their UI, make this 
particularly clear.

This leads to me wonder if, in actual use, even for customers who 
_could_ login to see complete results -- anyone ever does.

So very curious to get an answer from any existing customers as to this 
issue. Do the end-users realize they will get more complete results if 
they log in?   Do you have any numbers (or other info, even if not cold 
stats) on how many end-users choose to log in to see more complete results?

If nobody ever authenticates to see more complete results.... then the 
subset available to un-authenticated users essentially _is_ the product, 
the extra stuff that nobody ever sees is kinda irrelevant, no?

Anyone who is a current customer of Summon/Primo/EDS want to say 
anything on this topic? Would be helpful.
