ManticoreSearch VectorStore
ManticoreSearch is an open-source search engine that offers fast, scalable, and user-friendly capabilities. Originating as a fork of Sphinx Search, it has evolved to incorporate modern search engine features and improvements. ManticoreSearch distinguishes itself with its robust performance and ease of integration into various applications.
ManticoreSearch has recently introduced vector search capabilities, starting with search engine version 6.2 and only with manticore-columnar-lib package installed. This feature is a considerable advancement, allowing for the execution of searches based on vector similarity.
As of now, the vector search functionality is only accessible in the developmental (dev) versions of the search engine. Consequently, it is imperative to employ a developmental manticoresearch-dev Python client for utilizing this feature effectively.
Setting up environments
Starting Docker-container with ManticoreSearch and installing manticore-columnar-lib package (optional)
import time
# Start container
containers = !docker ps --filter "name=langchain-manticoresearch-server" -q
if len(containers) == 0:
!docker run -d -p 9308:9308 --name langchain-manticoresearch-server manticoresearch/manticore:dev
time.sleep(20) # Wait for the container to start up
# Get ID of container
container_id = containers[0]
# Install manticore-columnar-lib package as root user
!docker exec -it --user 0 {container_id} apt-get update
!docker exec -it --user 0 {container_id} apt-get install -y manticore-columnar-lib
# Restart container
!docker restart {container_id}
