Does anyone have experience with Adobe Live Search?

I was all ready to start a contract with Klevu for my B2B 2.4.4 site, but our Adobe rep threw up his hands and told me to use Live Search because it’s part of our commerce contract. Live Search has only been around for about a year, though, and I’m worried there are too many unknowns.

Does anyone have experience working with Adobe Live Search? Did you run into any roadblocks along the way? Does it provide better or equal results to any SAAS options you might have used before?

Would love to hear any thoughts.
