Search function to categorize by title, content, and tag

I was searching for this topic, and found this thread has been closed, I am starting to use Obsidian from 2023 this year, but I still found the search result not very clear, and doesn’t have different category by title, content and tag like this thread mentioned. the discussion from this thread which is exactly what I was looking for. But it’s not really impliment? why is this thread closed though?

It does. Please, read the documentation.
