## What it is
Ransack is a Ruby gem that adds object-based searching and filtering to Ruby on Rails applications via ActiveRecord. It lets developers build simple and advanced search forms using standard Ruby and ERB without external search infrastructure.

## Use cases
- add search to a Rails app
- build advanced filter forms for ActiveRecord models
- query records with dynamic conditions from URL params
- sort and filter tables without Elasticsearch
- create admin panel search interfaces

## When to choose
- you have a Rails app with ActiveRecord and need search/filtering
- you want to avoid running Elasticsearch or Algolia infrastructure
- you need SQL-based searching with i18n support

## When to avoid
- you need full-text search across large datasets
- your app is not Ruby on Rails
- you need fuzzy or typo-tolerant search

## Facets
- artifact type: library
- maturity: active
- function: search-engine, orm, web-framework
- domain: web-development, databases
- platform: ruby
- tags: activerecord, ruby-on-rails, sql-query-builder, search-forms, filtering, search, web-server
