Search using regex only searches open documents

• VSCode Version: Version 1.17.0-insider (Commit 67a8479)
• OS Version: Linux 4.12.13-1-ARCH Open Source VS Code #1 SMP PREEMPT Fri Sep 15 06:36:43 UTC 2017 x86_64 GNU/Linux

Steps to Reproduce:

1. Open a folder and ensure all editors are closed.
2. Open search, enable regex search and search for "\n" - You should get 0 results.
3. Open a few files in editors and search again, populated results will consist of only the open documents.

Note: sometimes it populates with just a single file, cannot consistently reproduce this.

Reproduces without extensions: Yes

This is expected - search doesn't normally support multiline search. But if the file is open, then search is done by the editor, which does support multiline search.

Good to know, I thought this was expected behavior but was confused when it did provide a result for the tsconfig.json file in the directory and thought something might have changed/was broken.

Is this intended functionality? or is the single result due to tsconfig.json being open in a hidden editor?

[roblourens]

That's interesting, I actually don't know why it would do that. It may be a bug in the search tool we use, but not a critical one. I can't reproduce, at least on MacOS

[SippieCup]

Yeah, definitely not a critical bug, that being said managed to reproduce consistently on MacOS.

1. Open a folder that has both a .ts file and a tsconfig.json file
2. Open the .ts file
3. Close .ts file
4. Search for "\n" with regex.

Ah, I can reproduce it now too. Apparently the tsconfig is open in the background, didn't realize it did that.
