We describe a high-precision Doppler search for giant planets orbiting awell-defined sample of metal-poor dwarfs in the field. This experimentconstitutes a fundamental test of theoretical predictions which will helpdiscriminate between proposed giant planet formation and migration models. Wepresent here details on the survey as well as an overall assessment of thequality of our measurements, making use of the results for the stars that showno significant velocity variation.Comment: 25 pages, 7 figures, accepted for publication in the Astrophysical Journa
