Searching a Flyway Database
As a database gets larger, and development more complex, so it becomes increasingly necessary to be able to search for strings in the source files and the database itself.

I'll show you how to answer these sorts of questions by running simple 'wildcard' searches on your Flyway migration files, or source files, as well as more targeted searches on certain parts of your database model.
