Work / How to find a job in Geology field? (Poland) [5]

Hello,
I am originally from India and from two years I am living in Częstochowa. I am trying to find a job in Poland since two years but unable to find. I have done masters in Petroleum technology, Graduation in Geology and Diploma course in Gemology. I am ready to work in any city of Poland. I am also ready to work in any field. I have accounts on job search sites like pracuja.pl but no one is contacting me. What can I do? Is my qualification is not good enough to get a job here?

I have temporary resident card of Poland until august 2017.
Please guide me. What else I have to do for getting a job here?
