[Numpy-discussion] Fwd: Looping and searching in numpy array

I need to loop over a numpy array and then do the following search. The
following is taking almost 60(s) for an array (npArray1 and npArray2 in the
example below) with around 300K values.
In other words, I am looking for the index of the first occurence in
for every value of npArray1.
for id in np.nditer(npArray1):
Is there anyway I can make the above faster using numpy? I need to run the
script above on much bigger arrays (50M). Please note that my two numpy
arrays in the lines above, npArray1 and npArray2 are not necessarily the
same size, but they are both 1d.
Thanks a lot for your help,
