Visual Studio Code searching with regular expression flag modifiers?

Question

For example, how do you set the i flag to perform a case insensitive match? Is it even possible?

In code I would usually do something like /needle/i

The Visual Studio Code documentation only makes a passing reference to the fact it uses the ripgrep regex engine. The docs there didn't help me either.

In the find panels, selecting the "Match Case" option turns a case-insensitive search into a case-sensitive search. So if the option is not selected, the search is case-insensitive.

I suppose behind the scenes this sets the regex i flag. Was curious if there was a more general way of applying regex flags though. Looks like they've provided a slightly simplified regex interface. Probably with good reason.

One of the first links in ripgrep's README is a link to the docs for its regex syntax. Among them are examples for applying flags within a regex. e.g., (?i)foo will match foo case insensitively. (This is fairly standard syntax for regexes, and is supported by both Perl and Python.)

Unfortunately, that syntax does not work in vscode. I do have the pcre option enabled. (?I)anything errors.
