Uppercase and lowercase letters of the alphabet are equivalent in the
Fortran character set. In other words, Fortran is case insensitive. This behavior is in contrast with case-sensitive languages, such as C++ and many others.

Often people try to index some content and then find it. If they cannot see the expected result, they try to troubleshoot the whole end-to-end process. The better way is to see whether the content actually indexed in the expected fields. This way it splits the problem into two: indexing and searchin...

Common table expressions support extracting portions of larger queries. For example:
WITH sales AS (
SELECT
orders.ordered_at,
orders.user_id,
SUM(orders.amount) AS total
FROM orders
GROUP BY orders.ordered_at, orders.user_id
)
SELECT
sales.ordered_at,
sales.total,...
