Dramatic spikes in searches, no increase in users

We just noted that over the past 2 weeks there have been two “spikes” in Algolia searches (and in our bill).

Our daily search volume looked like this:

Nov. 27: 165
Nov. 28: 222,440
Nov. 29: 316,270
Nov. 30: 784
Dec. 1: 913

There was a similar surge between Dec. 6-11.

Our other analytics tools showed no increases in traffic or users. What could explain this?
