  For more than three years now we have been conducting a spectroscopic survey
of detached eclipsing binaries (DEBs) from the All-Sky Automated Survey (ASAS)
database. Thousands of high-resolution spectra of over 300 systems were
secured, and used for radial velocity measurements and spectral analysis. In
our sample we found a zoo of multiple systems, such as spectroscopic triples
and quadruples, visual binaries with eclipsing components, and circumbinary
low-mass companions, including sub-stellar-mass candidates
