The present invention relates to an integrated full-text search
architecture that integrates full text search with database server
applications in a tight manner so that it becomes part of the server in
all aspects including storage, metadata, query processing, back/up
restore and resource management. This provides improved performance with
respect to queries as well as improved manageability. Furthermore, the
subject architecture is open and schema directed unlike other
conventional full-text search architectures. Accordingly, the full-text
search architecture enables expert users (e.g., search providers) to
define their own index structures as well as ranking algorithms.
