How to Include Installed Package Files in Unity Search Window?

I am trying to include files from installed packages in the Unity Search Window, but I am not sure how to configure this. I have searched through the preferences and the Package Manager settings, but I could not find a clear way to achieve this.

For example, I want to search for textures within the TextMeshPro package using the t:texture filter. However, it seems that the Search Window does not include files from installed packages by default.

Could someone please guide me on how to make installed package files, searchable within the Unity Search Window?

Thank you in advance for your help!

I solved it by opening the Search Index Manager, selecting Packages from the + and creating a new index.

I didn’t know about the existence of the Search Index Manager until I saw the forum post with the search tag… was it linked to the documentation? Anyway, that solved it.
