How can I increase the relevancy, in the search results, of more recent documents?

● Create a result biasing policy, which increases the relevancy of documents based upon the date

that they were last modified. Then, attach this policy to the appropriate front end.

● For URLs which have been added via a content feed you can add the following attribute to the

feed:

pagerank

○ This attribute specifies the PageRank of the URL or group of URLs. The default value is

96. A higher value specifies a higher PageRank. To boost the PageRank of the URL or

group of URLs, increase the value to a number between 97 and 100. To lower the

PageRank, decrease the value. The PageRank for a URL overrides one for a group.

● By using the automatic self-learning scorer.

○ If you enable ASR, the search appliance uses its automatic self-learning scorer. This

feature automatically analyzes user behavior and the specific links that users click on for

specific queries to fine tune relevance and scoring. The search appliance uses advanced

statistical regression to determine the statistical significance of user behavior, and adjusts

for trust bias (that is, users clicking on the first result solely because it's first). Thus, over

time, results become more and more precise without the need of administrator

intervention.
