[FLOW3-general] joins in select queries with TypoScript

[Robert Wildling]

Hi,

I am wondering if I am looking at the wrong place, but here:
http://typo3.org/documentation/document-library/core-documentation/doc_core_tsref/4.7.0/view/1/7/

there is nothing metioned about any join-possibilities in tables queries 
done with TS. There are other results out there, but where is the real 
docuemntation about it?

Thanks!
