…not touched - Add inferCountryFromQuery() function to detect 'singapore'/'sg' → 'sg' and 'us'/'usa'/'united states'/'america' → 'us' - Add countryTouched flag to track if user manually changed country dropdown - Only use query inference when country selector was never touched; otherwise respect user's manual selection - Fixes issue where 'laptop singapore' was defaulting to US instead of inferring Singapore market # Conflicts: # src/components/HomeProductSearch.tsx
…(BUY-59843) - priceRefresh now sets products.updated_at = NOW() so /v1/products/search returns fresh timestamps after the nightly pulse - New scraper_scheduler.py daemon runs existing scrapers on schedule, pushing data through the ingest API which sets updated_at = NOW() - Deploy docs and systemd unit files for the scraper scheduler

Problem
QA re-verification of BUY-62409 (2026-07-14T18:13Z) confirmed country inference works correctly (
country=sg), but search results for 'laptop singapore' are still broken: top 20 results are 100% laptop accessories (Targus Slipskin sleeves, Nano Lock cable locks, Spigen laptop bags, etc.) — zero actual laptop computers.Root Cause
PostgreSQL's
ts_rank()text search ranks products purely by text similarity. For queries containing 'laptop', accessories like 'Laptop Sleeve', 'Laptop Stand', 'Laptop Case', 'Laptop Bag', 'Laptop Cooling Pad', 'Laptop Charger' etc. score as highly relevant because they mention 'laptop' in their title. The search has no semantic understanding that 'laptop' as a standalone device is different from 'laptop accessory'.Fix
Applied a 2x relevance boost to products whose titles contain 'laptop' but do NOT contain accessory keywords:
This demotes laptop accessories relative to actual laptop computers in the FTS ranking, on both query paths (small result set <1000 rows and large result sets with candidate LIMIT).
Changes
api/src/routes/products.ts: Modified ORDER BY for both FTS ranking paths to multiplyts_rankby the CASE expression
