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"

Yes - you can use FParse::Value() to read a value from the command line, for example:

 int32 TheValueIWant = INDEX_NONE;
 if (FParse::Value(FCommandLine::Get(), TEXT("TheValueIWant="), TheValueIWant) == false)
 {
     TheValueIWant = DefaultValue;
 }

...will attempt to find a value after "TheValueIWant=" in your command line, and assign the found value to your local variable, and falls back to a default you've defined somewhere if it can't find the command line argument.
