SDSS-III BOSS provides homogeneous sample of 150,000 quasar spectra during the course of survey. The spectra give important information about the intervening absorbing material as well as about the quasars themselves. We can study the clustering properties of the intervening CIV absorbers found in the quasar spectra by cross-correlating the CIV absorber sample with the well-understood sample of quasars. Measuring the linear bias for the CIV absorber systems in a large homogeneous survey allows us to constrain the origin of these CIV absorber systems. It will also provide the constraints for the feedback processes in galaxy formation theory. We study the cross correlation in the range 2.1 < z < 2.6 as the abundance of CIV absorbers and quasars overlap at these redshift. We present the results from a CIV absorber clustering study from the first 2 years of BOSS data.
