I&#039;ve implemented an application wher I store documents (PDFs, Word Docs etc) as BLOBs in a SQL Server database. An ASP.NET application allows displaying, deleting etc. I now want to implement a search engine on the content in the database. Has anyone used any search engines to do this or should I look using a dedicated content/search application such as sharepoint that will integrate with ASP.NET.<BR>Most search engines I have looked at need the content stored on the file system rather than in a DBMS.
