JJ Food Service Ltd, a UK-based B2B food services company, utilizes the Elastic Stack for both log analytics and enhancing product search functionalities. By integrating Elasticsearch, Kibana, and Logstash, the company efficiently manages system logging and error detection, which allows for rapid response and improved system resilience. Innovatively, logs are piped directly into Redis Pub/Sub, bypassing file writing, and consumed by Logstash to feed Elasticsearch. The company employs Elasticsearch to power customer product searches, leveraging a microservices architecture that decouples search logic from server infrastructure. This setup enables flexible phased searches incorporating exact matches, store filtering, and fuzzy logic, significantly reducing zero-result instances and improving customer experience. The ongoing exploration of Elastic Stack's capabilities highlights the company's commitment to leveraging advanced technologies for operational excellence and customer satisfaction.
