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"

About FileReader and FlieWriter

i was build my replay system and i find a tutorial in wiki. https://wiki.unrealengine.com/Replay_System_Tutorial but when it comes to the following code, i couldn't fully understand what it means. TUniquePtr InfoFileArchive(IFileManager::Get().CreateFileReader(InfoFilename)); if (InfoFileArchive.IsValid() && InfoFileArchive->TotalSize() != 0) { FString JsonString; InfoFileArchive << JsonString; Info.FromJson(JsonString); Info.bIsValid = true; InfoFileArchive->Close(); } hope someone can explain how it works
