Google Search Appliance: Configuring GSA Unification 18
About Timeout Intervals and Result Biasing
The timeout interval and scoring bias parameters are set on the GSA Unification > Host Configuration
page for each search appliance in the configuration.
The timeout interval determines how long the primary search appliance waits before timing out a
request to a particular secondary node. Set the timeout interval to a lower value for co-located search
appliances and to higher values for search appliances that are physically distant from the primary
search appliance. Google recommends a 2 second timeout value for co-located search appliances.
The scoring bias parameter sets result biasing for the current node. Scoring bias changes the weight
assigned to results from a particular node in a unified environment when the final results ranking is
calculated. Less influence is a negative bias for results from the current node. No influence is a neutral
bias. More influence is a positive bias for results from the current node.
Unified Environment Checklist
This section provides a checklist of information you need to collect and decisions you need to make
before you set up a unified environment.
Task Description Your Values
Determine which Google Search
Appliance will participate in the
unified environment. Any Google Search Appliance model running software
version 6.0 or later can participate.
Determine the appliance IDs of
the participating search
appliances. The appliances IDs can be found on the Admin
Console under Administration > License.
Determine the host names or
public IP addresses of the
search appliances in the unified
environment. The host names or IP addresses are used during the
initial configuration of the unified environment.
Determine the network IP
addresses for the search
appliances. The network IP addresses are used for
communication among the search appliances in the
unified environment. The network IP addresses must
conform to the private address space as defined in
RFC 1918 and must not overlap with any other
private address space in use on your network.
Determine which search
appliance is the primary search
appliance in the unified
environment. You configure composite collections only on the
primary search appliance and searches are typically
entered on the primary search appliances.
Determine which collections on
each secondary search
appliance will be assigned to
composite collections on the
primary search appliance.
These collections will be served
from the primary search
appliance. These choices determine which collections are
searchable within the unified environment using
composite collections.
