How to search stories or tasks or bug based a keyword or string

[Nitin]

We have thousands of stories created and lots of them are completed too. Often we want to search the stories for a reference based on the TITLE, DESCRIPTION or COMMENTS added by various team members. For e.g. If I want to search all stories (irrespective DONE or IN-PROGRESS or just in BACKLOG) that has a string "foo" in it, then how do we search those stories. The string "foo" could be part of either description or comments or title of a story/bug/task.

We used to use PivotalTracker was easy to find stories based on a keyword or content.

Any help?

Closest I can get you is

text ~ foo and issuetype = story

The text keyword makes it search text contents, not just one named fields.
