Filtering
Pipelining
A language is more readable and predictable and simpler to write, if execution of results happen from left to right (or: top to bottom).
Therefore, FQL does not follow the the syntax order of SQL. A select can only happen after you acquire initial results. So,
typically, the from clause and the where clause happen before the first select. But using pipelining as a basic principle, you can sequentially use any filter clause, whether that's one or more select clauses, a where, a take, skip, 'order by', a 'group by', or a top levelfor clause.
