A high-performance FlutterFlow action that filters and ranks large string lists in real time. Tune relevance with a similarity threshold, control case sensitivity, cap results with limit, and enable preview for instant, keystroke-by-keystroke suggestions. Lightweight, offline-friendly, and perfect for powering fast, accurate search across big data.

Functionality

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

• Returns a ranked List of matches ordered by score

• Fuzzy matching with partial/substring and prefix weighting

• Unicode/diacritics normalization and optional case sensitivity

• Debounce-friendly; designed for realtime UI updates

• Early-return preview mode while the user types

• Hard limit to cap payloads for huge datasets

• Stable sorting; deterministic results for identical scores

• Works offline with local arrays or with cached API data

• Optional non-blocking execution to avoid UI jank

• Error/empty handling hooks and safe defaults

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

Use cases

• Global app search and command palettes

• E-commerce product, brand, and category lookup

• Country/city/tag pickers and long dropdowns

• Knowledge base / docs instant search

• Logs, settings, or feature flag finders in admin tools

• Contact directories and CRM lookups

• Analytics builders: metrics/dimensions search

• Offline catalogs in travel, media, or POS apps

• Autocomplete/typeahead backends for chat and forms
