Build local Hoogle DB despite error in Haddock

Is there a workaround to build a lokal Hoogle DB despite Haddock errors in some packages. For example, is there a workaround on how to exclude those packages from the Haddock sub-task during the lokal Hoogle DB build?

As a concret example:

$ stack hoogle
No Hoogle database yet. Automatically building haddocks and hoogle database (use --no-setup to disable) ...
classy-prelude-yesod-1.5.0: configure
classy-prelude-yesod-1.5.0: build
classy-prelude-yesod-1.5.0: haddock
Progress 1/2

--  While building package classy-prelude-yesod-1.5.0 using:

stack hoogle is approximately a helper around stack haddock then hoogle generate --local. If you can generate Haddock output only for the projects that work then you can manually hoogle generate --local. However, I'm not aware of any way to restrict stack haddock to only a subset, so it may not be practical.

Another approach is to hoogle generate <list of dependencies>, which will use the remote documentation rather than local, and thus will skip running Haddock.
