Elasticsearch

Overview

The Elasticsearch implementation provides a high-performance search solution for beneficiary data. It enables fast, fuzzy, and flexible searching across millions of beneficiary records with sub-second response times.

Key Features

• Lightning-fast search: Sub-second queries even with millions of records

• Fuzzy matching: Find beneficiaries even with spelling mistakes

• Flexible filtering: Search by multiple criteria simultaneously

• Real-time sync: Automatic indexing when beneficiaries are created/updated

• Scalable: Handles growing data volumes efficiently

Why Elasticsearch?

Business Problem

The existing database search was experiencing performance issues:

• Slow queries: Complex searches taking 5-15 seconds on large datasets

• Limited fuzzy matching: Exact matches required, causing missed results

• Database load: Heavy search queries impacting transactional operations

• Poor user experience: Users waiting too long for search results
