Q:

How to get all of the related posts on single or multiple subjects

I want to query Stack Overflow for all the posts on a single subject with accepted answers. For example, I want is to get all the posts on Stack Overflow which were related to PHP PDO. I saw somebody post a link in a reply and that link contains all the related posts. How do they do it and can I do it or are they operators on Stack Overflow?

A:

You can use the hasaccepted search keyword to search for questions with accepted answers, and you can search [tagname] to search on any tagname!
So, to search for all questions in  php-pdo with accepted answers you'd use:

[php-pdo] hasaccepted:1

as your search keywords
here's the whole list of search keywords (for meta)
and the same for the main site
edit: Or, if you're asking how to post a tag like this one: pdo then you simply use [tag:pdo] and markdown will convert it.
