A search service is designed to search for information in a specific corpus, or data set in order to provide fast and accurate results.
A search service is built by choosing, assembling, and configuring one or more agents from a wide range of ready-to-use modules. Each agent that is deployed is in charge of a specific data source (websites, file servers, archives, databases, XML streams, digital catalogs, and so on) called a feed.
This agent-based technology allows optimal processing of each data source by taking into account its constraints (access, security, format, structure, content). Agents use reply indexes produced by the Pipes and Filters (PaF) module.
The Back Office architecture includes a communication bridge with the AFS configuration. Detection mechanisms in the Back Office automatically retrieves AFS information withing seconds.
In AFS-BO, a service is the representation of an actual AFS service. The BO structure makes it possible to group services in projects associated to one or more organizations, and consequently to ta number of users and groups, in order to manage access rights. On the operations level, services are declared in the Back Office to display performance measures, hit-parade statistics, and query processes follow-up, as described in Checking Services Operations, Checking Services Performance, and Checking Services Hit-parade Statistics. They are also used to upload vocabularies, as described in Managing Vocabularies.
In the BO Administration screen, for a selected organization and a selected project, the services available are listed in the table in the SERVICES column.
