## What it is
Sifter.js is a JavaScript library for textually searching arrays and hashes of objects by one or more properties, with scoring, filtering, and sorting designed for autocomplete. It works both client- and server-side via UMD and supports diacritics, nested properties, and multi-field sorting.

## Use cases
- build autocomplete for a list of objects
- fuzzy search arrays of objects by property in javascript
- search objects with diacritic-insensitive matching
- sort search results by multiple fields
- filter a dataset client-side as the user types
- search nested object properties with dot notation

## When to choose
- you need lightweight, dependency-free fuzzy search/autocomplete over in-memory object collections
- you need diacritic-tolerant matching and smart match scoring
- you need the same search code in browser and node.js

## When to avoid
- you need full-text search over large datasets or an index - use a real search engine like lunr, flexsearch, or Elasticsearch
- you need active development or guaranteed maintenance - the project has no license file and infrequent releases
- you need server-side search over databases rather than in-memory arrays

## Facets
