This section describes the tasks involved in implementing the
Relevance Ranking feature.
About the relevance ranking feature
Relevance ranking allows you to control the order in which search results are displayed to the end user of a front-end application powered by the Oracle Endeca Server.
Relevance ranking modules
Relevance ranking modules are the building blocks from which you build the relevance ranking strategies to apply to your search interfaces.
Relevance ranking strategies
Relevance ranking modules define the primitive search result ordering functions provided by the Oracle Endeca Server. These primitive modules can be combined to compose more complex ordering behaviors called relevance ranking strategies.
This section provides some recommended strategies that depend on the implementation type.
Performance impact of relevance ranking
Relevance ranking can impose a significant computational cost in the context of affected search operations (that is, operations where relevance ranking is actually enabled).
