Challenge kya tha

A Coursera specialization and a Udemy course are structurally different products, and 200+ providers meant 200+ inconsistent schemas updating on their own cadences. On top of normalising all of that, search had to feel like Google.

Hum ne kya kiya

A plugin ingestion pipeline so each provider's weirdness stays contained, then a canonical schema and a scoring model that learns from behaviour.

Wo faisle jo aham the

  • One adapter per provider, one schema behind them

    Provider-specific adapters own auth, rate limiting and normalisation; everything downstream sees a canonical course with provider quirks in JSONB. Deduplication happens by fingerprint before indexing.

  • BM25 as a starting point, not an answer

    Custom Elasticsearch scoring layering rating, freshness, provider reputation and enrolment velocity on top of BM25 — with the weights set by A/B test rather than intuition.

Hum kya mukhtalif karte

Har mansoobe mein aisi aik baat hoti hai. Ise shaya karna hi asal nukta hai — jis case study mein koi pachhtawa na ho wo saboot nahi, tashheer hai.

Relevance is a product problem before it is an infrastructure one. Instrumenting what people actually clicked turned out to be worth more than any further tuning of the retrieval layer.
