Thank you. The indexes are built on top of either Faiss, Hnswlib or Annoy depending on the settings - https://neuml.github.io/txtai/embeddings/configuration/#ba

Thank you. The indexes are built on top of either Faiss, Hnswlib or Annoy depending on the settings - https://neuml.github.io/txtai/embeddings/configuration/#backend https://neuml.github.io/txtai/embeddings/configuration/#back... I've primarily focused on single query times, which have averaged around 5ms - 25ms depending on the size of the index. Queries can be batched so query times wouldn't increase linearly. You could batch quite a few and still get subsecond response times. All three libraries are approximate nearest neighbors but I know at least for Faiss, it can be configured to effectively be a precise query.
