| typedef long | idx_t |
| all indices are this type | |
splits input vectors in segments and assigns each segment to a sub-index used to distribute a MultiIndexQuantizer

Add n vectors of dimension d to the index.
Vectors are implicitly assigned labels ntotal .. ntotal + n - 1 This function slices the input vectors in chuncks smaller than blocksize_add and calls add_core.
| x | input matrix, size n * d |
Implements faiss::Index.
Definition at line 535 of file MetaIndexes.cpp.

overridevirtual |
query n vectors of dimension d to the index.
return at most k vectors. If there are not enough results for a query, the result array is padded with -1s.
| x | input vectors to search, size n * d |
| labels | output labels of the NNs, size n*k |
| distances | output pairwise distances, size n*k |
Implements faiss::Index.
Definition at line 580 of file MetaIndexes.cpp.

overridevirtual |
Perform training on a representative set of vectors
| n | nb of training vectors |
| x | training vecors, size n * d |
