Google Search Appliance: Getting the Most from Your Google Search Appliance Search Experience 48

Influencing Results Rankings

The Google Search Appliance enables you to influence the order in which the Google Search Appliance

ranks search results with its result biasing feature. Result biasing helps ensure that users see results

that are relevant to their interests or roles.

For example, given the search term “AltoStrat,” you might want code or design documents to appear

high in search results for the engineering group, while you might want product specifications to appear

higher for the marketing group. The following figure illustrates two different search results rankings for

the same search term, “AltoStrat.”

Because result biasing is specific to a front end, you can aim result biasing at a specific group of users.

The Google Search Appliance provides three ways for you to influence results ranking:

• Source biasing—based on how documents in a collection match certain URL patterns that you

provide, or the way documents are fed from a data source.

• Date biasing—based on document date.

• Metadata and entity biasing—based on metadata or entities associated with documents.

Because increasing the relevancy of specific documents may also decrease the relevancy of others, use

result biasing to boost scores of content sources that you are certain are more authoritative than other

sources.

Setting Up Result Biasing

Set up result biasing by performing the following steps with the Admin Console:

1. Creating a result biasing policy on the Search > Search Features > Result Biasing page. A result

biasing policy determines the source biasing, date biasing, and metadata and entity biasing settings

that are used with a front end.
