reading it) but searches give a big "Your search did >not match any

Huh.

I had that happen with Qt 4.7.4 on Windows.  I had to go into Qt Assistant's
Edit | Preferences | Documentation tab | Add button, and add all the .qch
files in the QtSdk/Documentation/ folder.

I think this is a bad bug that a freshly installed Qt doesn't show help
correctly, but thankfully it was an easy fix (after spending a few minutes
of CPU 'brain' time).
