Using the API Database
When invoked with the name of a class member, it lists the full name (including package and class) of each field and/or method that has that name.
When run with the name of a class, it lists the full name of every class in any package that has that name.
When called with a portion of a package name, it lists the names of all the packages that contain that string.

-p flag. Using the database connection

and executes the necessary SQL queries to return the desired
