Search LaTeX documentation with Alfred

I'm using Alfred v2 on Mavericks. I would like to use it to quickly locate documentation of LaTeX packages (PDF files). I have TeXLive 2014 installed in /usr/local/texlive/2014. I added /usr/local/texlive/2014/texmf-dist/doc/latex to Alfred's search scope, but I'm not having any success. I tried searching using open and the backtick (file search) to no avail. I tried rebuilding the OSX metadata, but not joy there either. The locate command-line utility quickly finds the files in question, e.g.:

$ locate thmtools.pdf /usr/local/texlive/2014/texmf-dist/doc/latex/thmtools/thmtools.pdf

I should add that Spotlight can't find the files either. Is it a matter of permissions?

$ ll /usr/local/texlive/ total 0 drwxr-xr-x 20 root wheel 680B Sep 21 11:51 2014

Thanks for any hint!
