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"

I agree. I've been waiting for a reply from anyone for over a month. I've spent countless hours searching through feeds to find a solution to a freezing issue very similar to your crashing issues. Only it freezes my entire computer and I do not get any crash reports that I can note. If you do find a solution, please place an update here so I can try it too.

I FOUND THE ISSUE..... it's not me, it's not my computer it IS NVIDIA GeForce thats required for Unreal Engine Epic Games Fortnite and...It is NOT compatible with windows 10... and it needs to be fixed on THEIR end before we can do anything about it![alt text][1]
