Day 12 Check Search Indexing and Retrieval

Check yourself

Ten questions on the two designs from Day 12, autocomplete and web search. Both build an index offline and refuse to compute anything at query time, and both serve about the same request rate. One replicates its index everywhere and the other splits it across thousands of machines, and the last questions are about why.

You will be asked 10 questions drawn from a larger bank, so a second attempt will not be the same paper. Answer from what the designs actually said, not from what sounds sensible in general.
