About

I am building Gram, a vector search engine in C++. I am also learning C++ and have an interest in search engines, so I started building it to learn by doing. It uses IVFPQ and AVX2 SIMD for CPU search. I started with IVFPQ and now I am working towards making it disk-based so it can work with bigger datasets. Would love to get some feedback :D
