Remove blog post from search engine

Dear Friends,

I’ve been asked by the contact person of a community first responders scheme to have the links to the blog post not anymore returned by search engines queries.

I read google pages and they describe how to prevent crawlers to index directories and/or sub-directories via the “robots.txt” file.

With the links generated by WordPress engine, how can I have this sorted?

Many thanks in advance!

Best regards,
