## What it is
The OpenSearch protocol specification, a collection of simple XML-based formats for sharing search queries and search results across websites, originally launched by A9.com in 2005. This repository hosts the specification documents (migrated from the original opensearch.org wiki) and is unrelated to Amazon's OpenSearch search engine project.

## Use cases
- implement OpenSearch description documents on my website
- share search results in a standardized format
- add OpenSearch autodiscovery to a browser search plugin
- read the OpenSearch 1.1 specification
- build a search client that consumes OpenSearch feeds

## When to choose
- you need to implement or reference the OpenSearch search-results syndication format
- you are building browser search plugins or search autodiscovery
- you need the canonical historical specification documents

## When to avoid
- you are looking for the Amazon OpenSearch search engine (use opensearch-project/opensearch instead)
- you need actively developed search software rather than a stable specification
- you need modern search APIs like GraphQL or JSON-based search
