How to search for regular expressions in search engines?

Question

Regular Expressions

I have a regular expression like '/^$/d', how can I search for the regular expression in a search engine? ['/^$/d'], "'/^$/d'" don't work properly.

Answer 1

But no way. The search engine searches for words and for it all sorts of quotes and other ampersands are garbage.

Answer 2

First, what are you trying to match with this regex?
Second, where are you trying to do it?
Third, why do you need it?
