Coarse-grained vs fine-grained
...an example, you will understand easily.
Fine-grained: For example, I have 100 services like findbyId, findbyCategry, findbyName...... so on. Instead of that many services why we can not provide find(id, category, name....so on). So this way we can reduce the services. This is just an example, but t...

This will work. You should call it like this:
$id = searchForId('100', $userdb);
It is important to know that if you are using === operator compared types have to be exactly same, in this example you have to search string or just use == instead ===.

How exactly does a generator comprehension work?
...>>> [x**2 for x in range(1,11)]
[1, 4, 9, 16, 25, 36, 49, 64, 81, 100]
here, range(1,11) generates the list [1, 2, 3, 4, 5, 6, 7, 8, 9, 10], but the range function is not a generator before Python 3.0, and therefore the construct I've used is a list comprehension.

mkarray [(+10), (+100), id] <*> mkarray [1, 2]
== mkarray [[11, 101, 1], [12, 102, 2]]
But if you make it a monad, you could get a dimension mismatch. I suspect that examples like this are rare in practice.
