5.8 Using different index/search engines with the Broker


By default, Harvest uses the Glimpse index/search subsystem. However, Harvest defines a flexible indexing interface, to allow Broker administrators to use different index/search subsystems to accommodate domain-specific requirements. For example, it might be useful to provide a relational database back-end, or a Latent Semantic Indexing [9] back-end.


At present we distribute code to support an interface to both the free and the commercial WAIS index/search engines, Glimpse, and Nebula [6] gif.

Below we discuss how to use WAIS instead of Glimpse in the Broker, and provide some brief discussion of how to integrate a new index/search engine into the Broker.
