## What it is
Sphinx is an open-source full-text search server written in C++, providing fast indexing and querying of structured and unstructured data. This repository hosts the legacy 2.x branch, which is no longer actively developed; active development happens in the closed/delayed-FOSS 3.x releases.

## Use cases
- add full-text search to a website or application
- index millions of SQL database records for fast search
- run a standalone search server with an SQL-like query language
- build autocomplete and faceted search features
- replace MySQL full-text search with a faster engine

## When to choose
- you need a mature, self-hosted full-text search server with low resource usage
- you are maintaining an existing deployment already built on Sphinx 2.x
- you want SQL-database integration for search indexing

## When to avoid
- you need the latest features or bug fixes - the 3.x release is developed separately with delayed source access
- you want a fully open-source actively maintained project - this branch is effectively unsupported since 2018
- you prefer an ecosystem with modern tooling like Elasticsearch or Meilisearch

## Facets
- artifact type: service
- maturity: maintenance
- function: search-engine, http-server
- domain: databases, developer-tools
- platform: windows, cross-platform
- tags: full-text-search, c-plus-plus, indexing, legacy-branch, search, linux, macos
