Google Search Appliance: Configuring GSA Unification 15
5. On a client machine that uses the Kerberos protocol for user authentication, open a browser. For
example, this might be a Windows client machine that uses Active Directory on a Windows server
for authentication.
6. Make sure the browse is configured as described in “Kerberos-Based Authentication” in Managing
Search for Controlled-Access Content.
7. On the primary search appliance, go to the search page.
8. Type a search query that is expected to return results from URLs crawled on the primary and
secondary search appliances. If such a query does not exist, search for a term that is expected to be
found only on the secondary search appliance.You should not be prompted for a user name and
password and the search should return results that were crawled on the secondary search
appliance.
About Composite Collections
A composite collection is a collection configured on the primary search appliance of a unified
environment that includes one or more collections defined on one or more of the secondary search
appliances. You can create two types of composite collections:
• Collections that include only collections from the secondary search appliances in the unified
environment
• Collections that include collections from the primary and secondary search appliances
You create composite collections to ensure the following:
• User search queries are distributed to the correct search appliances.
• The correct collections on those appliances are searched.
There are no limits to the number of composite collections you can create on the primary search
appliance. A particular collection on a secondary search appliance can be a member of more than one
composite collection.
When you create composite collections containing collections from both the primary and secondary
nodes, you designate logical operators governing which collections on which search appliances are
searched in response to a query.
For example, you might have a search appliance with three collections, called X, Y, and Z.
• X AND Y AND Z means that a document must be present in all three collections to be found.
• X OR Y AND Z is interpreted as (X OR Y) AND Z and means that the document must be in either X or
Y and also in Z to be found.
In another example, you might have two search appliances, 1 and 2, where collections X and Y are on
search appliance 1 and collection Z is on search appliance two. X AND Y OR Z means that documents
must be in both the X and Y collections or in the Z collection.
The AND operator can be used only with collections on the same search appliance, such as X and Y in
the immediately previous example. You cannot use AND with collections on different appliances.
