golang全文搜索--使用sphinx

不多废话,测试环境 `ubuntu 13.10`

## 安装
sudo apt-get install sphinxsearch

## 配置
nano /etc/sphinxsearch/sphinx.conf

# 数据源配置
source default
{
type = xmlpipe2
xmlpipe_command = /path/xmlpipe2
xmlpipe_fixup_utf8 = 1
}

# 索引配置
index default
{
type = plain
source = default

# 索引文件路径
path = /path/filename

# 不存储文档信息
docinfo = none

#最小索引词长度
min_word_len = 2

charset_type = utf-8

# 指定utf-8的编码表
charset_table = 0..9, A..Z->a..z, _, a..z, U+410..U+42F->U+430..U+44F, U+430..U+44F

# 简单分词，只支持0和1，如果要搜索中文，请指定为1
ngram_len = 1

# 需要分词的字符，如果要搜索中文，去掉前面的注释
ngram_chars = U+3000..U+2FA1F

}

## xmlpipe2的格式

...

...
...
...

只要配置文件中 xmlpipe_command 字段配置的可执行文件输出为相应的xml流即可,这样几乎适配了所有数据源

## 生成索引

$ indexer default

## 配置searchd

编辑sphinx配置文件,添加:

## 监听地址

searchd
{
# 监听地址(Unix socket)
listen = /var/log/searchd.sock

# 日志文件
log = /var/log/searchd.log

# 查询日志
query_log = /var/log/query.log

# 客户端读取超时时间
read_timeout = 5

# 客户端请求超时时间
client_timeout = 3000

# PID 文件
pid_file = /var/log/searchd.pid
}

## 运行searchd

$ sudo searchd

searchd status

## golang客户端

package main

import (
"github.com/yunge/sphinx"
"log"
)

func main() {
// 链接参数
opts := &sphinx.Options{
Socket: "/var/log/searchd.sock",
Timeout: 5000,
}

// 创建客户端
spClient := &sphinx.Client{Options: opts}
if err := spClient.Error(); err != nil {
log.Fatal(err)
}

// 打开链接
if err := spClient.Open(); err != nil {
log.Fatal(err)
}

// 获取实例信息
status, err := spClient.Status()
if err != nil {
log.Fatal(err)
}

for _, row := range status {
log.Printf("%20s:\t%s\n", row[0], row[1])
}

// 查询
res, err := spClient.Query("33", "default", "Test Query()")
if err != nil {
log.Fatal(err)
}

log.Println(res)
}

输出:
