Here you can define a new crawled index by giving it a unique name and specifying the Web addresses, or URLs, of the Web sites that you want Web Search to index.
Enter a unique name, such as Sales or Marketing. If you are going to create a larger number of indexes, you might consider using a numbering system, such as 001, 002, 003, etc.
Enter the Web address, or the actual Uniform Resource Locator (URL) of the Web sites that you want indexed.
