I am wondering if there are any updates on the progress of the JSR proposed in this message? Small quote:
The Search Specification will be an API for composing and federating search queries to a set of search providers, and aggregating returned results. The main goal is to support search as a way of integrating enterprise systems. Examples of use cases include a Java web application or portal that offers combined Web, enterprise, and site search, or a front-end Java customer support application that offers search of a variety of back-end enterprise applications, as a way of locating all available information on a particular customer.
