Learn tab in Search tool (cntrl+F) does not give any results

[Dacruiser]

Hi.

Whatever I type in the search field after hitting (cntrl+f), and selecting the learn tab, I get the following message:  "Sorry no results were found.  Try searching again with fewer terms or check for typos"    I get this even when typing in easily identified terms such as "masks", "layers" or "crop" in the search field.    I do get results in the All tab or Photoshop tab but nothing in the Learn tab.  Any idea on how to fix this?    Thanks for your help
