Robots.txt advice

[eLab_London]

Hey Guys,

Have you ever seen coding like this in a robots.txt, I have never seen a noindex rule in a robots.txt file before - have you?

user-agent: AhrefsBot

User-agent: trovitBot
User-agent: Nutch
User-agent: Baiduspider
Disallow: /

User-agent: *
Disallow: /WebServices/
Disallow: /*?notfound=
Disallow: /?list=
Noindex: /?*list=
Noindex: /local/
Disallow: /local/
Noindex: /handle/
Disallow: /handle/
Noindex: /Handle/
Disallow: /Handle/
Noindex: /localsites/
Disallow: /localsites/
Noindex: /search/
Disallow: /search/
Noindex: /Search/
Disallow: /Search/
Disallow: ?

I have never seen a noindex rule in a robots.txt file before - have you?
Any pointers?

Best I could find was-

Unlike disallowed pages, noindexed pages don’t end up in the index and therefore won’t show in search results. Combine both in robots.txt to optimise your crawl efficiency: the noindex will stop the page showing in search results, and the disallow will stop it being crawled

Never seen this, doubt it's any useful as this isn't part of any search engines recommended statements to use. I don't think this would have any impact on what search engine robots would look at as it's not a statement in the robots.txt documentation.
