Diagnose Query Failures in an E-Commerce Search Box

FreeVerified credential2 weeksIntermediate

Overview

What this challenge is about.

You receive 6 months of anonymized query logs (~480 million rows): query string, language hint, results-shown count, top-3 product clicks, and add-to-cart events. Build a notebook that finds zero-result and low-CTR queries, clusters them (embedding + HDBSCAN or simple TF-IDF clustering), tags each cluster with a dominant failure mode, and quantifies revenue impact by cluster. Deliver: notebook, a labeled cluster spreadsheet, and a 5-page diagnosis memo with prioritized fixes (typo tolerance, query expansion, synonym tables, language detection) and rough engineering-cost estimates.

The Brief

What you'll do, and what you'll demonstrate.

Find and quantify the dominant failure modes behind the failing 3% of search queries, with prioritized fixes.

Earning criteria — what you'll demonstrate

  • Profile a real query log for failure modes
  • Cluster queries and tag the dominant failure mechanism per cluster
  • Quantify revenue impact of each failure cluster
  • Translate IR failure analysis into prioritized engineering work
