Fast, Tiny, & Good fuzzy search for JavaScript.

Fast: <1ms to search 13,000 files.
Tiny: 1 file, 0 dependencies, 5kb.
Good: clean api + sorts results well.

They're indexable to get each normal result keysResult[0].highlight() // 'Liechi Berry' keysResult[1].highlight() // 'Raises Attack when HP is low.' keysResult.score // .84 keysResult.obj.title // 'Liechi Berry' ``` ## How To Go Fast · Performance Tips ```js let targets = [{file: 'Monitor.cpp'}, {file: 'MeshRenderer.cpp'}] // filter out targets that you don't need to search! especially long ones! targets = targets.filter(t => t.file.length < 1000) // if your targets don't change often, provide prepared targets instead of raw strings! targets.forEach(t => t.filePrepared = fuzzysort.prepare(t.file)) // don't use options.key if you don't need a reference to your original obj targets = targets.map(t => t.filePrepared) const options = { limit: 100, // don't return more results than you need! threshold: .5, // don't return bad results } fuzzysort.go('gotta', targets, options) fuzzysort.go('go', targets, options) fuzzysort.go('fast', targets, options) ``` ### Gotcha `result.score` is implemented as a getter/setter and stored different internally `r.score = .3; // r.score == 0.30000000000000004` ## Star History [![Star History Chart](https://api.star-history.com/svg?repos=farzher/fuzzysort)](https://star-history.com/#farzher/fuzzysort) ### Changelog #### v3.1.0 - Automatically handle diacritics / accents / ligatures #### v3.0.0 - Added new behavior when using `keys` and your search contains spaces! - Added `options.key` can now be a function `{key: obj => obj.tags.join()}` - Removed `fuzzysort.indexes` & Added `result.indexes` (as a getter/setter for GC perf) - Removed `fuzzysort.highlight()` & Added `result.highlight()` - Changed scoring: score is now a number from 0 to 1 instead of from -Infinity to 0 - Changed scoring: substring matches are even more relevant - Changed scoring: `straw berry` now matches great against `strawberry` - Changed scoring: tweaked the scoring quite a bit - `result.score` is behind a getter/setter for performance reasons - Fixed minor issues #### v2.0.0 - Added new behavior when your search contains spaces! - Added fuzzysort.min.js - Now depends on ES6 features - Removed `result.indexes` & Added `fuzzysort.indexes` (improved GC performance) - Completely Removed `options.allowTypo` - Completely Removed `fuzzysort.goAsync` - Completely Removed `fuzzysort.new` - Rewrote the demo #### v1.9.0 - Even faster - Added `options.all` - Deprecated/Removed `options.allowTypo` - Deprecated/Removed `fuzzysort.goAsync` - Changed scoring: boosted substring matches - Changed scoring: targets with too many beginning indexes lose points for being a bad target - Changed scoring: penality for not starting near the beginning - Changed scoring: penality for more groups - Fixed "Exponential backtracking hangs browser" #### v1.2.0 - Added `fuzzysort.highlight(result, callback)` #### v1.1.0 - Added `allowTypo` as an option #### v1.0.0 - Inverted scores; they're now negative instead of positive, so that higher scores are better - Added ability to search objects by `key`/`keys` with custom weights - Removed the option to automatically highlight and exposed `fuzzysort.highlight` - Removed all options from `fuzzysort` and moved them into `fuzzysort.go` optional params #### v0.x.x - init
