Hi Jake,
Self Service is designed to prevent the end user from being able to search for anything that is based on the standard processes. They will only see content that has been created through the normal knowledge activities of article and document creation. This is to ensure that there are no issues of security about the data that is contained within the IPC processes. The fundamental premise in SD is that you generate knowledge articles from other processes rather than make those processes searchable. I would go so far as to say that this is also best practice to ensure that the quality of the knowledge that is being made available to your end users is appropriate.
If you make an Incident process searchable, you will get everything that has been entered without any checks or QA. I wouldn't want to cast doubt on your analysts, but in general the average analyst in the street will not add information to an incident resolution field that is fit for user consumption, especially when they are under pressure. I would strongly advise that you create the ability to generate knowledge articles from IPC processes and QA them through the article process before they are published to your customers. I can assure you that you will benefit in the long run as it will avoid any unforeseen surprises. The creation of effective knowledge is a key part of providing the end user with access to self help through the web and it does take some effort and planning on the part of the IT organisation.
