Lightbulb Case-Insensitive Regex Flag \\i ?

When using regex in jDownloader rules, I've found posts that claim that starting the expression with \\i makes the regex case-insensitive.

I've tested this dozens of times and I cannot get it to work. If I remove the
\\i" from the beginning of a regex expression, it will work fine (when the case matches). When I add only the \\i - the expression no longer works.

I've never been able to confirm this is the correct method; my only source comes from searches on this forum.

Am I doing something wrong / should I be using a different code?

Thank you in advance

@MediaFanatic:
please see Java Pattern docs
docs.oracle.com/javase/7/docs/api/java/util/regex/Pattern.html#CASE_INSENSITIVE
Quote:
Case-insensitive matching can also be enabled via the embedded flag expression (?i)
by default the pattern will auto enable DOTALL and CASE_INSENSITIVE modifier but you can
disable them by disabling them inline, for example

@Jiaz - Thank you, as always, you provided exactly the answer I needed and it now works perfectly!

I was not aware that jDownloader rules use the standard Java Pattern/flags, despite searching on this topic.

For sake of others who might be Googling for this information, I'll include some additional keywords:

Regular Expressions Case-Insensitive Search - Solved:

Prefix the Regex expression with (?i) for example (?i)(.*)?(SearchString)(.*)?$

Note: Due to the dotall, we explicitly refer to the end-of-line with pessimistic capture prior, to avoid capturing new-line characters.

Names and URLs don't have newlines in them
