If you have all the filter values for COL1 in an array called FILTVALS, you could do this:
var cond = entity.col1.$eq(FILTVALS[0]);
FILTVALS.splice(0,1);
var cond2 = FILTVALS.reduce(function(prev, curr){ return prev.$or(entity.col1.$eq(curr));
},cond);
var qry = entity.$query().$where(cond2);
qry.$execute();
