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 scope 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 scope or the All packages scope:
Note: You can search for either Unity packages or Asset packages. The filter you choose defines where the Package Manager searches:
|Where the Package Manager searches:
|Any package on the Unity Package Manager registry, in a scoped registry, and anywhere in the project, including under the
|Any package installed or embedded in your current project (including locally installed packages).
Packages folder in your current project.
|The list of purchased or downloaded assets for your account (your My Assets page).
|Any built-in package.
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.
Enter the version number in version order (MAJOR.MINOR.PATCH). For example, typing 1 returns all packages with versions beginning with 1 (for example, 1.0.0, 1.3.2, 1.10.1, and 10.0.0 all match but not 0.1.0).
