# 5.1. Server packages

The package `groonga` is the minimum set of fulltext search engine. If you want to use groonga for server use, you can install additional preconfigured packages.

There are two packages for server use.

- `groonga-httpd` (nginx and HTTP protocol based server package)
- `groonga-server-gqtp` (GQTP protocol based server package)

There is the reason why groonga supports not only GQTP but also two HTTP server packages. GQTP - Groonga Query Transfer Protocol is desined to reduce overheads and improve performance. But, GQTP is less support of client library than HTTP protocol does. As HTTP is matured protocol, you can take advantage of existing tool and there are many client library (See related projects for details). If you use `groonga-httpd` package, you can also take benefits of nginx functionality.

We recommend to use `groonga-httpd` at first, because it provides fullfilling server functionality. If you have performance issues which is derived from protocol overheads, consider to use `groonga-server-gqtp`.

> Note

> In the previous versions, there is a `groonga-server-http` package (simple HTTP protocol based server package). It is now marked as obsolete, please use `groonga-httpd` packages instead. `groonga-server-http` package became a transitional package for `groonga-httpd`.
