improve response speed on QA lookups

[michelleif]

QA lookups sometimes take a long time to respond. investigation currently underway by QA team on where the lag is. also unclear if some of the problem is on Sinopia side.

the slow response seems to be responsible for unexpected results, where you get results based on the first few characters you type, but the lookup doesn't seem to catch up to the rest of what you typed.

Review our code and look for performanc bottlenecks. (Up to 2 hour evaluating.)

Note in particular, the use of Promises.all(). May need to create additional followup tickets.
