Setting this per-user system policy specifies the order in which the installer searches three types of sources. The types of sources are:

"n" – network

"m" – media (CD-ROM or DVD)

"u" – Uniform Resource Locator (URL)

For example, to search network sources first, media sources second, and URL sources last set this policy to a value of "nmu". To omit searching for a particular source type, leave out the corresponding letter from the value.

If SearchOrder is not set, the default search order is network, media, and then URL.
