• Implemented multi-field search, fuzzy matching, field boosting, and aggregations to enhance the search experience.
• Integrated n-gram analyzers to improve partial word matching, making search results more intuitive and responsive.
• Optimized indexing and query performance to handle millions of daily active users (DAU) across 500+ enterprise customers.
• 2) Architected the KM–NLP Sync Process Using RabbitMQ
• Engineered a batch-based sync mechanism to efficiently update the KM system with the latest NLP articles.
• Designed an S3-based chunking system, where large article datasets were split into smaller chunks and stored in S3.
• Processed article chunks asynchronously using the message broker RabbitMQ, replacing the old synchronous approach.
• Deployed two separate containers for KM:
• KM API container (for handling API requests).
• KM worker container (dedicated for sync processing).
• This architecture allowed parallel processing of article updates, improving performance and reducing sync latency by 90 percent.
• The sync process ensures that KM articles remain up-to-date with NLP, enabling accurate chatbot responses.
