Can Virtuoso be used as a Search Engine?
Yes,Virtuoso can create a free text index on any XML or text column of atable. Additionally, DAV repository contents are by default indexed.Virtuoso free text search includes word proximity searches, and theability to combine XPATH, Free Text, and Regular Expressions, ifrequired, in the same query. The long and short of this is thatyou can harvest and then index any form of text based web data(HTML, XHTML, XML etc.) stored in Virtuoso.
