index") What it means by "Index index" I think that is c code arian1020. FAISS (short for Facebook AI Similarity Search) is a library that provides efficient algorithms to quickly search and cluster embedding vectors. To save time, you can generate an index file based on the vector file and load the index file to Faiss-Server. . It contains algorithms that search in sets of vectors of any size, up to ones that possibly do not fit in RAM. This notebook shows how to use ConversationBufferMemory. If you wish use Faiss itself as an index to to organize documents, insert documents, and perform queries on them, please use GPTVectorStoreIndex with FaissVectorStore. Well compute the representations of only 100 examples just to give you the idea of how it works.

The process is fairly simple in 2 lines of code with FAISS (Facebook AI Similarity Search), our in memory vector store, and a search function coupled with the.

So, given a set of vectors, we can index them using Faiss then using another vector (the query vector), we search for the most similar vectors within the index.
