sphinx-0.99 + ultrasphinx

一、Installing Sphinx

1.Extract everything from the distribution tarball (haven't you already?) and go to the sphinx subdirectory:
$ tar xzvf sphinx-0.9.9.tar.gz
$ cd sphinx

2.Run the configuration program:
$ ./configure
There's a number of options to configure. The complete listing may be obtained by using --help switch. The most important ones are:
    * --prefix, which specifies where to install Sphinx;
    * --with-mysql, which specifies where to look for MySQL include and library files, if auto-detection fails;
    * --with-pgsql, which specifies where to look for PostgreSQL include and library files.

3.Build the binaries:
$ make

4.Install the binaries in the directory of your choice:
$ make install

after successfully install:
[/usr/local]whereis searchd
searchd: /usr/local/bin/searchd
[/usr/local]
[/usr/local]which is searchd
/usr/local/bin/searchd

二、install dependencies and config

1.install ultrasphinx
cd rails_app
script/plugin install git://github.com/fauna/ultrasphinx.git
#script/plugin install svn://rubyforge.org/var/svn/fauna/ultrasphinx/trunk


2. 修改Sphinx配置文件并创建索引
安装完Ultrasphinx之后，将：vendor/plugins/ultrasphinx/examples/default.base
复制到：config/ultrasphinx/default.base

修改Model代码，加入全文检索支持：
假设我有一个Model叫做Project，其中有一个属性叫做name，我希望对这个属性做全文检索，我在project.rb中加入一行：is_indexed :fields => ['created_at', 'name']
For more index options, see ActiveRecord::Base .is_indexed.
/home/simon/NetBeansProjects/my_sphinx/vendor/plugins/ultrasphinx/lib/ultrasphinx/is_indexed.rb



生成配置文件：rake ultrasphinx:configure
这条命令执行后，在config/ultrasphinx下创建了一个development.conf，这个文件就是Sphinx的配置文件。

创建索引：rake ultrasphinx:index
索引相关的文件创建在base指定的目录


3. 启动Sphinx的searchd服务：
rake ultrasphinx:daemon:start

这个时候会在3313端口启动一个searchd，搜索请求将会全部发送到这个端口来执行。
也可以自己手工来启动searchd
searchd


4. 测试
script/console
search = Ultrasphinx::Search.new(:class_names => 'Project')
search.run
search.results

如果执行这几条语句都没有报错，那么安装就成功了。
