Complete and searchable User Manual?

As a long time user, most of the time I don't need any help.

But as soon as I do, I get stuck in the online resources.

There does not seem to be a complete online manual/documentation for After Effects.

We are directed to the communities, and general support databases.

E.g.

1 - Choose After Effects Help... in the  Help Menu

2 - this redirects to the support site, choose 'User Guide' (right button)

3 - See how the Search field is not for this Guide, but for 'Adobe Support'

4 - Type 'Layer Styles'

5 - See how no relevant search results show up. (the 2nd result even loops back to 2) 

Does anyone know where to find the manual, without irrelevant user experiences and reports?
