Indexing/Displaying Results From External Content

Hello all,

I've followed the code from this example:

docs.sitefinity.com/for-developers-index-external-content

I've been able to index 1 document with the following fields.    

Title = "test"

Content="test"

Summary = "test"

When I search for "test", that document comes up fine.  When I then change the fields:

Title = "test2"
Content="test2"
Summary = "test2"

and then search again for "test", I would expect 2 results, but I just get 1 document back for "test2".   I'd like to pass a lot of documents to get indexed, but not sure why only the last indexed item displays.  

Please help.

Anyone?
