The Universal Connector enables you to connect visual search to any existing third party system like Elastic Search, MySQL or others. The idea is to generate a search set of image IDs in your existing search engine and pass the results as image IDs to pixolution flow. Instead of using pixolution flow as a standalone search system you connect its visual search capabilities to your existing system using the Universal Connector.
You can keep your implemented business logic and search criteria and extend your system with the functionality provided by pixolution flow. Please refer to Workflow for an architecture overview.
