\FinderIndexerDriverSqlsrv

Indexer class supporting SQL Server for the Finder indexer package.

The indexer class provides the core functionality of the Finder
search engine. It is responsible for adding and updating the
content links table; extracting and scoring tokens; and maintaining
all referential information for the content.

Note: All exceptions thrown from within this class should be caught
by the controller.
