Regex find within a file produces different results to Find in Files

• OS Version: Windows 7

It appears that find in files produces different results when using a regex search with new lines \n or lookbehind ?!. See the screenshot below for an example. I would have expected find in files to return a result here.

I am aware that find in files will omit results if the result set is too large, that is fine and to mitigate this have have specified the directory, again see screenshot.

Steps to Reproduce:

1. Ctrl+Shift+F to open find in files
2. Switch to regex mode
3. Enter a regex with a newline or lookbehind, there maybe others but these are the only ones I have encountered
4. Hit enter.

Depending on the regex you will either get a handful of results or non at all. However if you search in the file directly it will find all of the occurrences.

Could not reproduce. @colinbull Does the file use Windows line delimiters?

[colinbull]

Yes the file I'm looking at does. But it has the same behaviour even if I use [\r\n]+ which is what I originally tried.

Sorry the screenshot was taken during some experimentation.

@colinbull Multi-line search is not supported in Find in Files feature - See #13155

If I am not wrong, look behind expressions are not supported in javascript regex.
