WebIndexing By default, pgvector performs exact nearest neighbor search, which provides perfect recall. You can add an index to use approximate nearest neighbor search, which trades some recall for performance. Unlike typical indexes, you will see different results for queries after adding an approximate index. Two keys to achieving good recall are: Web6 feb. 2024 · pgvector introduces a new data type called vector.In the code above, we create a column named embedding with the vector data type. The size of the vector defines how many dimensions the vector holds. OpenAI's text-embedding-ada-002 model outputs 1536 dimensions, so we will use that for our vector size.. We also create a text column …
