JQL is the query language for Jira searches

project = "Make Money" AND (assignee = currentUser() OR assignee = U618777)

...is an example of JIRA Query Language I suppose. This has a cheatsheet of things you may filter against when searching tickets. To do something like the example above, have your pairing partner click on his avatar at the upper right and then pick "Profile" to get at the "Username" for the end of the search and look at any one JIRA ticket for your project to get the magic string for the project name which will appear above the largest text on the page offering the ticket's name as a hyperlink. Clicking the hyperlink takes one to a URL and therein projectKey= appears as a URL line variable and the setting at the right of the equals sign is going to be an encoding that leads all of the ticket numbers for the project. If you try to put it in the search bar some intellisense will find the magic string for the project name for you, but really you can just paste the magic string from the hyperlink in and skip that step. See this for how to get at statuses.
