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"

You have a few different options. You could add a tcp/ip listen server to UE4 in C++ and then have "software A" call that listen server and then raise the event to your blueprint. That is probably the best solution, but will likely take a bit of work. If you don't want to write a lot of C++ in UE4, then you could use the VaREST plugin to poll a service that runs in "software A". This is what I do and it is quote simple. If you write "software A" in C# .NET you could build an app to do what you want in just a dozen lines of code.
