Select (retrieve) all records from multiple schemas using Postgres

I have a PostgreSQL database with some schemas, like below:

My_Database
 |-> Schemas
    |-> AccountA
    |-> AccountB
    |-> AccountC
    |-> AccountD
    |-> AccountE
           .
           .
           .
    |-> AccountZ

All schemas have a table called product which has a column called title. I would like to know if is possible to execute a select statement to retrieve all records from all schemas with a certain conditional.

The only way I found until now is to run a query account by account, like below.

SET search_path TO AccountA;

SELECT title FROM product WHERE title ILIKE '%test%';

Schemas are created dynamically, so I don't know their names or how many of them exist.
