About 'get_indice_pairs' function

[Machinerr]

Hi, thank you for your contribution.
I got some trouble when I read the code of function 'get_indice_pairs', do you have any document about this function? I just can't understand what is the output index_0 and index_1, and the function of it?
looking forward to your reply.

Please read our paper for the detail of stratified sampling strategy. The result of the function 'get_indice_pairs' means the indices of the queries (index_0) and keys (index_1), where the query-key pairs need to perform dot-products.
