 ## Search Issues
 
-You can search for issues containing a given phrase across many repositories:
+You can search for issues containing a given phrase across many
+repositories:
 
 ```csharp
-// a search 
-var request = new SearchIssuesRequest("linux");
+// searching without specifying a term
+var request = new SearchIssuesRequest();
 
-// it is highly recommended to search in specific repositories
+// you should focus your search to a specific repo

-By default, search will return the first page of results and use

-request.Page = 2;
-request.PerPage = 30;
+// if you're searching for a specific term, you can
+// focus your search on specific criteria
+request.In = new[] {
+    IssueInQualifier.Title,
+    IssueInQualifier.Body
+};
+
+// you can restrict your search to issues or pull requests
+request.Type = IssueTypeQualifier.Issue;
+
+// you can filter on when the issue was created or updated
+var aWeekAgo = DateTime.Now.Subtract(TimeSpan.FromDays(7));
+request.Created = new DateRange(aWeekAgo, SearchQualifierOperator.GreaterThan)
+
+// you can search for issues created by, assigned to
+// or mentioning a specific user
+request.Author = "davidfowl";
+request.Assignee = "damianedwards";
+request.Mentions = "shiftkey";
+request.Commenter = "haacked";
+
+// rather than setting all these, you can use this to find
+// all the above for a specific user with this one-liner
+request.Involves = "davidfowl";

+// by default this will search on open issues, set this if
+// you want to get all issues
+request.State = ItemState.All;
+// or to just search closed issues

+## Search Pull Requests
