For example we want to update for John, for the book The Insider, pages from 200 to 250 . What will be the query ?

1. What's the difference between repeated and nested? Is it something must be nested before it can be repeated?
2. What is the FROM table, UNNEST syntax? Sometimes i see FROM table CROSS JOIN UNNEST, or FROM table LEFT JOIN UNNEST too.
3. What is FROM X, Y syntax?

good explanation about repeated fields. how can we query --> Give me users who either have "The insider" or "The Alchemist". The result should return Krishna and John
