The previous fuzzy search implementation was too permissive — searching for 'cashu' returned 13+ irrelevant results (Club Orange, CornyChat, Podcast Index, etc.) because the subsequence matching gave non-zero scores to characters scattered across long descriptions. Replace the hand-rolled fuzzyScore/fuzzySubsequence with @nozbe/microfuzz, a tiny zero-dependency library with a 'smart' strategy that filters out poor-quality matches. Also use microfuzz's built-in highlight ranges for more precise search result highlighting. Before: 'cashu' → 13+ results (mostly noise) After: 'cashu' → 3 results (Shopstr, Satsback, Cashu Redeem)

Problem
Searching for
"cashu"returned 13+ irrelevant results (Club Orange, CornyChat, Podcast Index, Podhome, Highlighter, Slice, BTCPay Server, Zeus, Bitcoin Well, Alby PaidMCP…) because the hand-rolledfuzzySubsequence()gave non-zero scores to characters scattered anywhere in the text.Solution
Replace the hand-rolled fuzzy search with
@nozbe/microfuzz— a tiny (zero-dependency) fuzzy search library with a"smart"strategy that filters out poor-quality subsequence matches.Changes
src/lib/discover.ts— RemovefuzzyScore,fuzzySubsequence,scoreAppForQuery,fuzzySearchMatches(~80 lines). AddsearchApps()using microfuzz withstrategy: "smart"and aWeakMapcache for the searcher instance.src/components/app-card.tsx— Replace hand-rolledbestMatchIndex+ single-span highlighting with microfuzzHighlightRangesfor precise multi-range highlighting.src/App.tsx— Compute search results map and passtitleRanges/descriptionRangestoAppCard.Before → After (
