Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

Repro steps are perhaps incomplete. Callstack mentions STutorialContent - do you have any tutorials open at that time? Could you try without that? Also, could you try that in 4.8?

I have already finished the tutorial; none of the tutorials are running at the time, but this doesn't help. This error keeps popping up:

Version 4.8 is not the final version, I cannot use it. Version 4.7 is what I need.

That is baffling. What is your desktop environment and the OS? Can you repro that in Ubuntu (either Unity or KDE)?
