Quantization in qg-l2-float.cpp

MINGRUI001 opened this issue · comments

For the sample of qg-l2-float, it shall be to construct a quantization graph and search on it. However, in the searching part (index.search(sc), line 99 of qg-l2-float.cpp), it is still to search the original graph without considering the quantization codes. I have also checked that some PQ-related functions, e.g., createDistanceLookup, are not called. Isn't it? Thanks.

Thank you for your investigation. I have released v2.1.4 which resolves this issue.
