Search outside database!
The strong feature of DBSight is searching databases, but because DBSight is only for database, it has been the shortcoming also.
But thing's changed! Now DBSight can search outside database also!
Basically you just need to implement a simple abstract java class, where you can retrieve content from any data source, like files on disk, XML feeds via HTTP, etc.
The API is simple, yet able to handle incremental indexing and a re-creating index. You just need to select the content and submit it to DBSight. The content is processed in a streaming fashion, without consuming too much memory. DBSight will handle uniqueness checking and content updating in the background.
