Please describe what is going wrong and provide some steps to reproduce the issue

I am experiencing this issue as well. It started for me today when I updated VS Code and installed this morning's VS Code Insider. It occurs on both VS Code and Insiders.

Steps to Reproduce:

1. Open a Folder (mine happens to be through samba)
2. Ctrl + Shift + F
3. Expand elipse and add files to include. Mine is *.cfm,*.cfc also occurs with using **/*.cfm,**/*.cfc (Formatting is hard)
4. Search for anything (like 'a' or a space)
5. See no results unless they exist in a file opened in a tab.

Are there any errors in the search output pane?

This seems to only happen when using "Files to include" filter with search in files over the network via UNC paths. It occurs whether I run VS Code normally or as administrator. When I use "whoami" in VS Code's Powershell it shows my proper domain and user which has permissions to the linux server through samba. The filtered search works normally on local directories and the output is basically identical (replace UNC path with local path by opening local folder and it works).

Here is the search output (github code tag not working for me):

`

rg --hidden --heading --line-number --color 'ansi' --colors 'path:none' --colors 'line:none' --colors 'match:fg:red' --colors 'match:style:nobold' --ignore-case -g '//server/folder/**/*.cfm/**' -g '//server/folder/**/*.cfm' --max-filesize '314572800' --no-ignore --follow --fixed-strings -- 'a' '\\server\folder'
- cwd: c:/
- Sibling clauses: {}
No files were searched, which means ripgrep probably applied a filter you didn't expect. Try running again with --debug.

Somehow the slashes get flipped

Hello, same problem: happens on a local folder.
Search works if I disable Ripgrep.

This is the output:

`rg --hidden --heading --line-number --color 'ansi' --colors 'path:none' --colors 'line:none' --colors 'match:fg:red' --colors 'match:style:nobold' --ignore-case -g '!/Scripts//.git' -g '!/Scripts//.svn' -g '!/Scripts//.hg' -g '!/Scripts//CVS' -g '!/Scripts//.DS_Store' -g '!/Scripts//node_modules' -g '!/Scripts/**/bower_components' --max-filesize '17179869184' --no-ignore --follow --fixed-strings -- 'write' 'c:\Scripts'

• cwd: c:/
• Sibling clauses: {}
  c:\Scripts: Access is denied. (os error 5)`

Same here, search works only in opened files. I am using Linux version.

Same here in 1.18.1, please like the topic, so it get better priority!

Happened after switch to multi-root project structure. Maybe its not related, but some projects are searchable, some are not.

1.19.1 - still does not work. Does nobody using an integrated search feature?)

This issue is tracking the search includes not working correctly in UNC paths. @davide-rota 's issue may be with searching in a onedrive-tracked directory, like #35433?

@FelikZ please open a new issue with as many details about your setup as possible, including the info from the search output pane as above.
