A next-gen FlutterFlow action that delivers smarter, faster, ranked search over very large lists. V2 adds token-aware scoring, typo tolerance, diacritics handling, and ultra-smooth “as-you-type” previews—so users get relevant results instantly without blocking the UI.

Functionality

• Inputs: query (String), items (List<String>), limit (Int), threshold (Double 0–1), caseSensitive (Bool), preview (Bool)

• Returns a ranked List with scores optimized for relevance

• Fuzzy matching: prefix/substring weight, token & word-start boosts, minor-typo tolerance

• Unicode & diacritics normalization (ñ = n, é = e) with optional case sensitivity

• Real-time preview stream for keystroke-by-keystroke suggestions

• Hard limit to cap results; stable sort for deterministic ties

• Debounce-friendly, non-blocking execution to prevent UI jank

• Pluggable highlighter: exposes match ranges for bold/mark UI

• Works offline on device; also pairs with cached API data

• Safe defaults & guards for empty queries and giant datasets

• Drop-in integration with text fields, lists, typeahead, and pickers

Use cases

• Global search bars and command palettes

• Massive product, movie, book, or music catalogs

• Admin tools: settings, logs, and feature flag finders

• Country/city/tag pickers and long single/multi-selects

• Knowledge base & documentation instant search

• CRM/contact directories and user lookup

• Analytics builders: metrics/dimensions/segments search

• Offline catalogs for travel, retail, or POS apps

• Autocomplete/typeahead backends for chat and forms

• Education apps searching courses, lessons, or terms
