Most people who have created websites using the Indexing Server are familiar with the IXSSO query and util objects.  .NET provides a wrapper for these functions dubbed CISSO.

One of the great things about the CISSO object is that ability to use the Intellisense in Visual Studio.  It sure makes it a lot easier to find that function name that you were looking for.

In order for you to be able to use the CISSO object, you must include a reference to the Interop.Cisso.dll assembly.
