Creating Content Source and Scope - SharePoint 2007 [Part 1]

Creating a Content Source
In the Central Admin, go to Shared Services.

1) Go to Search Administration page.

2) Select Content Sources

Any web application you create is added into the address list in the default content source which is "Local Office SharePoint Server Sites" 

If you need to have separate search for you web application you can have a separate content source and add a separate search scope for that. This approach can also be used if you need to target your search to retrieve data from target lists.

3) create a new content source, by clicking on the "New Content Source"

Here I have created two new content sources targeting two different search results.

To add web application URL's to the content source you need to go inside the default content source and remove the web application URL first from there, save the content source, and then come back to the newly created content source and include the URL there.
