Service Developer Information

Overview

The FAST query listener service allows Aspire to mimic a FAST ESP query server. This means that you can use FAST clients to submit queries to Aspire.

This application utilises HTTP Feeders to accept queries meant for a FAST Search Server and places them in an AspireObject, and processes them using the workflow engine. Data returned is transformed using XSL to the format expected by a FAST query client.

This application will most likely be used in conjunction with the Query Executor Application Bundle to send queries on to the server after processing.
