The Include results from circular traversals option
enables you to include elements that occur more than once in each traversal. If you do
not select this option, those elements are returned just once in each traversal. For example, continuing with the same model, let's say you initially want to return
data for any meetings that Mohamed Atta attended but once you have those results, you
want to see all attendees of a particular meeting. Your initial query might look like
this: The results show that he attended a meeting in Kandahar in December 1999. Now you want to
know who else attended that meeting. Your second query would look like this: Note that if you leave the Include results from circular
traversals box unchecked, Mohamed Atta's relationship will not be returned
because that relationship (Person:Mohamed Atta->Attended->Meeting:Kandahar) was
already traversed in the first step of the query. However, if you check that box,
Mohamed Atta's relationship will be returned in addition to those for the other three
attendees:
