This document provides technical information for the new module "Similarity search with perceptual hashes (POC) " which includes the plugin "Similarity Search”. The module is designed to generate embeddings using perceptual hashes for objects during the ingest process, storing the hash in the record metadata and offering an API method to retrieve similar objects for an existing object. This module is the basic version for similarity search whereas Similarity search using Open AI (POC) offers the premium version.

Description

Similarity search consists of asking for an existing object the most similar objects. See /wiki/spaces/CS/pages/4586110979for details.

Activation

This feature will be automatically activated on mh-uat for the organisation mh-uatb during the sprint release 24.4/3secondary organisation on integration environments.

  1. Create the following field definitions

    1. MapField named Dynamic.EmbeddingsPoc

    2. VectorField named Dynamic.EmbeddingsPoc.PerceptualHash with dimensions = 64 and index = true

    3. Publish them

  2. Enable the module SIMILARITY_SEARCH_PERCEPTUAL_HASHES_POC for the customer’s organisation. See the REST document for information on how to do that.

  3. Ingest new objects
