Indexing external content

Enonic version: 6.4.2
OS: Mac and Linux

The rumor says it should be easy to index external content, to make it searchable within Enonic,
but I could not find anything regarding that here:

Is it possible? If so please provide documentation and perhaps an example.
Will/can a copy of the indexed data be stored in Enonic too? If so can I/how do I expose that data via controller -> view.


Only content stored in Enonic is searchable, so it has to be imported somehow. Depending on your needs; either as structured data or possibly as just a simple holder content with a single text content field. Importing data into the system could be done by transforming external data into valid import-files or use the API to create it. I guess the latter would be the most convenient way.
