Clarification in Composer proxy Repository

[svinothmca]

Hello Team,

We have installed composer plugin in Nexus Dev and created a proxy repo to download the PHP libraries.

From the nexus proxy repository it is only listing down the packages and the URL is not working if we pass any arguments but it is working in External URL

Eg

URL works to list down the packages - https://nexus.com/repository/packagist-org/packages/list.json

URL doesn't work in filtering the packages - https://nexus.com/repository/packagist-org/packages/list.json?vendor=spatie

Also it throws 404 error in the below URL

https://nexus.com/repository/packagist-org/search.json?query=php-amqplib

Where else it is working in external proxy URL

Working fine -

https://packagist.org/packages/list.json?vendor=spatie

https://packagist.org/search.json?query=php-amqplib
