"There is quite a bit of lag time on the front end, and I understand that it's doing a lot in the background, however in this day if something doesn't happen instantly it feels slow. We also use the knowledge library side, and currently you have to tag it, but it won't allow you to really search multiple words at one time, which is frustrating. So you have to tag specific words in hopes that people will search for the right word."
