## What it is
Chewy is a high-level Elasticsearch ODM (Object Document Mapper) for Ruby, built on top of the official elasticsearch-ruby client. It provides ActiveRecord-style index definitions, automatic index updates on model changes, bulk/atomic reindexing, and a chainable query DSL.

## Use cases
- index ActiveRecord models into Elasticsearch with automatic sync on save
- denormalize related data like tags into a single searchable document
- perform full reindexing using the Elasticsearch bulk API
- build chainable, lazy Elasticsearch queries with an ActiveRecord-like DSL
- keep indexes updated atomically when multiple related models change

## When to choose
- you use Ruby/Rails with ActiveRecord and want idiomatic Elasticsearch integration
- you need automatic index updates triggered by model changes
- you want bulk and atomic reindexing without writing raw client code
- you prefer a query DSL over hand-writing JSON query bodies

## When to avoid
- you use a language other than Ruby
- you need a search engine other than Elasticsearch
- you want a lightweight wrapper and prefer calling the raw Elasticsearch client directly
- you need OpenSearch-specific features outside the supported Elasticsearch versions

## Facets
- artifact type: library
- maturity: active
- function: orm, search-engine, database-driver
- domain: databases, web-development, backend
- platform: ruby
- tags: elasticsearch, odm, activerecord, indexing, rails, search
