You can use the search box at the top of the Package Manager window to find any packages that match the text you enter. The Package Manager updates the package list as you enter text, displaying every package within the current context that matches. For example, if you enter web in the search box, the list displays different results depending on whether you choose the Built-in packages list context or the Unity Registry list context:
You can look for a package by its name or its display name. You can search for either the display name as it appears in the Package Manager window or, for Unity packages, the registered package name that begins with com.unity.
Your search text could match the beginning, middle, or end of the package’s name. The Package Manager updates the list of packages dynamically.
Note: You can search for either Unity packages or Asset Store packages. The list context you choose defines where the Package Manager searches:
|Where the Package Manager searches:
|The list of packages on the Unity registry
|Any scoped registry defined for your project
|The package cache and the
Packages folder under your current project
|The list of Asset Store packages available with your Unity account
|The list of built-in packages on the Unity registry
