So here's a question that I haven't been able to find the answer to anywhere:

What field(s) does Windows 10 use to index files by whenever performing a start menu search? The obvious answer would be that it's indexing by filename and filename alone, but I'm not entirely so sure. If it's not clear what I mean, observe the following example below:

As of right now, the ONLY folder that I have Windows 10 indexing on my computer is the "C:\ProgramData\Microsoft\Windows\Start Menu\Programs" folder (and all of its contents). This is because I put shortcuts to all of my programs in there. But look at this:

enter image description here

Notice that the shortcut with the filename "Epic Games Launcher.lnk" showed up first, before the shortcut with the filename "Unreal Engine.lnk." Now,for those who don't know, there is a relationship between the Epic Games Launcher and Unreal Engine (the Epic Games Launcher is what you use to install Unreal Engine), but I still don't understand why it appears in the search first despite not having the word "Unreal" anywhere in its filename.

I noticed that the "description" of the "Epic Games Launcher.lnk" that can be viewed when opening up the properties says "UnrealEngineLauncher," but whenever I type "UnrealE" into the search, nothing shows up at all, so I don't assume that Windows is using this "description" field to index the shortcuts. So I have no idea what it's really doing.

Does anybody understand this, and, apart from deleting the Epic Games Launcher shortcut, does anybody know how to make Windows 10 index by filename only? Thanks.

  • At a guess, perhaps it's looking at the executable path in the .lnk file. – Anaksunaman Apr 18 '18 at 5:59
  • @Anaksunaman I doubt that can be it; the path in this case is: "C:\Program Files (x86)\Epic Games\Launcher\Portal\Binaries\Win32\EpicGamesLauncher.exe" which does not contain the text string "unreal." Further, if I name a shortcut something completely arbitrary and then type that name into the search, it still shows up. So it must be indexing by something in addition to the filename, but whatever it is still mystifies me. I suspect it could be a property somewhere that the epic games launcher itself set whenever I installed it, but who knows where that is? – ereHsaWyhsipS Apr 18 '18 at 6:19
  • So, in general, I'm wondering what Windows is actually doing whenever you do these searches. I really want to find out! – ereHsaWyhsipS Apr 18 '18 at 6:21

    Can you reproduce this? (Search "web browser" and get Edge & IE only) – guest-vm Apr 27 '18 at 18:30

    @guest-vm while I agree with your overall philosophy, from my perspective, the bounty is relatively inconsequential. That's why I didn't attempt to write an answer, instead. However, I still wanted to help the OP as much as possible, and that's also why I didn't flag the post as too broad even though it contains multiple questions. The ultimate query is as follows: "Does anybody know how to make Windows 10 index by filename only?" The genuine answer should be "no," because unfortunately that isn't possible (regardless of the native Windows 10 index methods that piqued their curiosity). – Run5k Apr 28 '18 at 21:01

You have two parts to your question. First, "does anybody understand this." According to Microsoft:

"By default, all the properties of your files are indexed, including file names and full file paths. For files with text, their contents are indexed to allow you to search for words within the files."

Of course, this is not as specific as we might like, but it is easy to see how Unreal Engine could be associated with the Epic Games Launcher, since the indexing is this broad.
This means that the hypothesis "that Windows is using this 'description' field to index the shortcuts" is in fact correct.
Fortunately Windows does allow some control over this behavior, even if it is not as much as one might like.

That brings us to the second part of the question: "Does anybody know how to make Windows 10 index by filename only?"

The short answer to this part of the question is "no."
Windows does allow some modification of indexing behavior, but not in great detail. On Windows 10 (and some earlier version) in your Indexing Options, in Advanced, you can change indexing behavior on a per-file-extension basis. Unfortunately, it does not allow fine-grained choices such as "only by filename." Your two choices are "index properties only" and "index properties and file contents." In your case even the more restricted "index properties only" option will include the description, because that is part of the file's properties.

There is an additional piece of information relevant to this whole discussion: why does "Epic Games Launcher" not only show up, but show up as the best as the Best Match? Briefly put, "Best Match" is a potentially misleading label. This is a result field that attempts to find what the user is most likely interested in, not some simple ranking of how closely a result matches the search term.
