Google Search Appliance: Getting the Most from Your Google Search Appliance Search Experience 50
Segmenting the Index
The Google Search Appliance enables you to divide your search index into sections and provide search
across different content to different groups of users with its collections feature. A collection is a subset
of the complete search index.
Search results from a collection have the same relevance ranking as full index searches. Only the
content searched differs because it is restricted to the individual collection’s content. By searching a
collection, users get relevant search results more quickly than by searching the entire index.
Using collections, you can show different results to different users. For example, you might create
collections such as:
• “Corporate Policies,” for any staff to search for policy documents
• “Engineering,” for technical users and other user who need to search for engineering documents
• “Europe Offices,” for users who are geographically located in the European offices
• “Marketing,” for marketing staff to search for marketing documents
• “Sales,” for sales staff to search for sales documents
To search a collection, a user can select the collection name from a pull-down menu on the search box,
as illustrated in the following figure.
Collections are independent of front ends. However, you can use a custom front end with a specific
collection to help improve searches and enhance results.
Setting Up a Collection and Adding a Pull-Down Menu
To set up a collection, specify URL patterns that it should include. If you set up more than one collection,
the same entry can appear in multiple collections. You can set up 200 collections for a search index.
