Please read the FAQ which explains what a good question should contain. Please add some code, the result image that you have and so on. Having said that, you know there exists a documentation right? For SIFT it clearly show which parameters you have. You have to define how many features you actually want using the first parameter. The operator option even returns a set of keypoints, just look at the size of that to know the amount of features returned.
