Google Search Appliance: Use Advanced URL Patterns
A "collection" is a subset of all pages indexed by the Search Appliance. You configure your collection to include URL patterns matching all Web pages within your organization. URL patterns make it easy to include entire Web sites and sections of Web sites in one step. Note that it may take several hours for the Search Appliance to populate your collection with documents from the main index after you add new URL patterns.
Occasionally in the Admin Console you will need to enter URL patterns, such as when defining the set of Web pages that make up your collection. A pattern allows you to match sets of URLs that share something in common: the same server, the same server and directory, a certain file name extension, and so on.
The built-in Help pages on the Search Appliance already provide a wide range of URL pattern examples and explanations — simply click a Help link next to a text field that requires URL patterns. As we discover them, we will add examples of undocumented, advanced URL patterns that we find particularly useful.
