The only book on the market to fully cover SQL Server 2008’s Full-Text Search, a feature becoming increasingly important in the face of the growing need to manage large volumes of XML, PDF, and other free-format, digital data. Full-Text Search is so important, that one Microsoft Product Manager refers to it as “the largest and most challenging improvement” in SQL Server 2008. Hillary Cotter and Michael Coles’ book will be the go-to book for developers wishing to take advance of this increasingly key feature in SQL Server.
