sphinx API中文

sphinx 全文搜索引擎：顧名思義，是作收索用的，由於普通的搜索在數據量小的時候，能應對自如，可是當數據量上千萬，或者上億的時候。純粹的sql搜索顯得緩慢，無力。於是爲了提升用戶體驗，增快用戶的搜索速度，出現了sphinx 。簡單的例子好比大型網站的首頁搜索。

1.安裝須知

Coreseek發佈了3.2.14版本和4.1版本等多個版本
3.2.14版本是2010年發佈的，它是基於Sphinx0.9.9搜索引擎的。4.1版本是2011年發佈的
，它是基於Sphinx2.0.2之後的

2.使用sphinx須要的工做

1.檢查中文環境語言
    2.升級依賴包
    3.下載並安裝mmseg（coreseek所須要的詞典）
    4.安裝coreseek的csf-3.2-14（也就是sphinx）
    5.安裝配置sphinx並運行生成相應的索引
    6.啓動sphinx，php文件調用sphinx服務便可
    7.配置php支持sphinx （或者引用sphinx類直接調用sphinx也行）
    
注意事項：①、採用API調用，如使用PHP、java等的API函數或方法查詢。優勢是可沒必要對mysql從新編譯，服務端進程「低耦合」，且程序可靈活、方便的調用；須要二次查詢。
二次查詢注：到如今發佈版本爲止——sphinx-0.9.9，sphinx在檢索到結果後只能返回記錄的ID，而非要查的sql數據，故須要從新根據這些ID再次從數據庫中查詢，

3.檢查環境語言

[root@localhost ~]# locale
LANG=en_US.UTF-8
LC_CTYPE="en_US.UTF-8"
LC_NUMERIC="en_US.UTF-8"
LC_TIME="en_US.UTF-8"
LC_COLLATE="en_US.UTF-8"
LC_MONETARY="en_US.UTF-8"
LC_MESSAGES="en_US.UTF-8"
LC_PAPER="en_US.UTF-8"
LC_NAME="en_US.UTF-8"
LC_ADDRESS="en_US.UTF-8"
LC_TELEPHONE="en_US.UTF-8"
LC_MEASUREMENT="en_US.UTF-8"
LC_IDENTIFICATION="en_US.UTF-8"

#如上顯示英文的（若是是中文的直接進行下一步）
LANG=en_US.UTF-8
LC = en_US.UTF-8
#要配置成中文的
export LANG=zh_CN.UTF-8
export LC_ALL=zh_CN.UTF-8

#運行以後
[root@localhost ~]# export LANG=zh_CN.UTF-8
[root@localhost ~]# export LC_ALL=zh_CN.UTF-8
[root@localhost ~]# locale
LANG=zh_CN.UTF-8
LC_CTYPE="zh_CN.UTF-8"
LC_NUMERIC="zh_CN.UTF-8"
LC_TIME="zh_CN.UTF-8"
LC_COLLATE="zh_CN.UTF-8"
LC_MONETARY="zh_CN.UTF-8"
LC_MESSAGES="zh_CN.UTF-8"
LC_PAPER="zh_CN.UTF-8"
LC_NAME="zh_CN.UTF-8"
LC_ADDRESS="zh_CN.UTF-8"
LC_TELEPHONE="zh_CN.UTF-8"
LC_MEASUREMENT="zh_CN.UTF-8"
LC_IDENTIFICATION="zh_CN.UTF-8"
LC_ALL=zh_CN.UTF-8

4升級依賴包

yum -y install glibc-common libtool autoconf automake mysql-devel expat-devel
# 手動升級 autoconf
tar -zxvf autoconf-2.69.tar.gz
cd autoconf-2.69
./configure
make
make install

5.安裝coreseek的mmseg

tar -zxvf coreseek-3.2.13.tar.gz
cd coreseek-3.2.13
cd mmseg-3.2.13/
./bootstrap    #輸出的warning信息能夠忽略，若是出現error則須要解決
./configure --prefix=/usr/local/mmseg3
make
make install

# 檢測是否安裝完成
mmseg
提示：-bash: mmseg: command not found

# 問題解決方法
ln -s /usr/local/mmseg3/bin/mmseg /bin/mmseg

# 
mmseg

# 顯示如下內容表示安裝成功
Coreseek COS(tm) MM Segment 1.0
Copyright By Coreseek.com All Right Reserved.
Usage: mmseg <option> <file>
-u <unidict>           Unigram Dictionary
-r           Combine with -u, used a plain text build Unigram Dictionary, default Off
-b <Synonyms>           Synonyms Dictionary
-t <thesaurus>          Thesaurus Dictionary
-h            print this help and exit

安裝csf-3.2-14

cd csft-3.2.13/
sh buildconf.sh    #輸出的warning信息能夠忽略，若是出現error則須要解決 
./configure \
--prefix=/usr/local/sphinx \
--without-unixodbc \
--with-mmseg \
--with-mmseg-includes=/usr/local/mmseg3/include/mmseg/ \
--with-mmseg-libs=/usr/local/mmseg3/lib/ \
--with-mysql=/usr/local/mysql/ \

make
make install


#./configure --prefix=/usr/local/sphinx/ --with-mysql=/usr/local/mysql/ --enable-id64 
make 
make install 
# 注意1：採用這種方式安裝不支持中文分詞。
# 注意2：--enable-id64 系統是64位，開啓後Sphinx存儲模塊能夠支持4-5G,不開啓支持2G左右，不開啓檢索效率會高些，通常狀況下建議不開啓

# 錯誤：
collect2: ld 返回 1 
make[2]: *** [indexer] 錯誤 1 

# 修改configure文件中：
LIBS="$LIBS -L/usr/local/lib"
# 改成：
LIBS="$LIBS -liconv -L/usr/local/lib"

6.再測試下mmseg分詞和coreseek搜索

cd testpack 
cat var/test/test.xml  #此時應該正確顯示中文 
/usr/local/mmseg3/bin/mmseg -d /usr/local/mmseg3/etc var/test/test.xml 
/usr/local/sphinx/bin/indexer -c etc/csft.conf --all 
/usr/local/sphinx/bin/search -c etc/csft.conf 網絡搜索 
此時正確的應該返回 
words: 
1. '網絡': 1 documents, 1 hits 
2. '搜索': 2 documents, 5 hits

3.sphinx.conf配置文件

[root@localhost ~]#cd /usr/local/sphinx/etc #進入sphinx的配置文件目錄
[root@localhost etc]# cp sphinx.conf.dist sphinx.conf #新建Sphinx配置文件
[root@localhost etc]# vim sphinx.conf #編輯sphinx.conf
