Hello
Im new to this forum and tried to search for an answer of my questions but cannot find matching results, or too much answers,
So it dont seem to work like I think 
many thanks in advance!
Isn't it like a Google search? Or DuckDuckGo - which I use.

It does accept regular expressions and has done so for some time.
It may not use ALL the regex as I have not tried them all.
EDIT.
Asked higher up if it uses all or a subset of REGEX.

I'm curious about how that works.
Does it expand the REGEX into a search string and then do a search with the string?
I wonder is there an example that illustrates the benefit of using a REGEX?

I am not sure myself Robin which is why I asked upstairs.
It may just be a subset of regex so may be limited.

Thx, will try again - google, duk²go is far away from regexpr.

I'm still curious to know how a regex might be used for searching. Is it just a shortcut alternative to writing a long search term?

somehow, but it will be a very loong search term .e.g with regexp. you can include, exclude a set of letters, phrases, length of a word, count of repetition etc. to get a set of matching text. .
example: text must contain any of SR04, SR05, SR08 ... SR0[458]
You know I wanna use DuckDuckGo but does it give results similar to Google? I'm just worried about that...By the way Firefox + DuckDuckGo is extraordinary...

That suggests to me that you want the combined results from several separate searches each one looking for a different word. That would be a large job for a large database and then there is the problem of how to prioritize the results.
Google's big strength is that it presents what it considers to be the most useful results first. Before Google showed what could be done the search engines were almost useless.

sure, it is diffucult but Im not an admin nor a forum-software developer so dont know the size of this forums DB.
Google had it success because of the robots, collecting websites and buildung hashtables all the time, other machines were seraching on request.
A forum can make restrictions, has all the data stored in one place (server) etc. So maybe a forum-Software developer will decide in future to offer regexp for restrected set (category, not later than 1 year) etc.?
There mihght be too less need for such fetaures? dont know.
But this was a question and not a request

I understand. But I assumed your question was prompted by a specific idea of how it could be useful to you.
I'm just curious about this because I had not seen regexp's mentioned in the context of a web search.
