Sphinx的一个应用实例

我把我blog的数据(中英文混合)导出, 作为数据来源, 来说明sphinx的使用.

准备数据源

导入数据:

mysql -u root -p test < wp_posts.sql

配置Sphinx

配置data source:

source blog
{
type = mysql
sql_host = localhost
sql_user = root
sql_pass = xxxx
sql_db = test
sql_port = 3306
sql_query = /
SELECT ID, post_author, UNIX_TIMESTAMP(post_date) as date_added, post_content from wp_posts
sql_attr_uint = post_author
sql_attr_timestamp = date_added
sql_query_info = SELECT * FROM wp_posts where ID=$id
}

配置index:

index blog
{
source = blog
path = /usr/local/sphinx/var/data/blog
docinfo = extern
charset_type = zh_cn.utf-8
charset_dictpath = /usr/local/sphinx/dict
}

注意: 字典的目录要加上.

索引

./bin/indexer --config ./etc/sphinx.conf blog

如果没有错误, 会看到:

Coreseek Full Text Server 3.0(beta)

using config file './etc/sphinx.conf'...

indexing index 'blog'...

collected 165 docs, 0.2 MB

sorted 0.0 Mhits, 100.0% done

total 165 docs, 164834 bytes

total 0.099 sec, 1670067.52 bytes/sec, 1671.75 docs/sec

测试搜索

./bin/search -c ./etc/sphinx.conf -i blog 苹果

输出:

Coreseek Full Text Server 3.0(beta)

using config file './etc/sphinx.conf'...

0x815e1f8index 'blog': query '苹果 ': returned 1 matches of 1 total in 0.005 sec

displaying matches:

启动searchd

./bin/searchd

使用调用API

#!/usr/bin/python

if sys.getdefaultencoding() != 'utf-8':
reload(sys)
sys.setdefaultencoding('utf-8')
import web

)
app = web.application(urls, globals())
con = MySQLdb.Connect(host="localhost", port=3306, user="root", passwd="xixihaha", db="blogdata")
class index:
def GET(self):
r_info = ''

s_result = ''
return render.index(r_info=r_info, e_info=info, s_result=s_result)
def POST(self):
i = web.input()
if i.keyword == '':
raise web.seeohter('/')
e_info = ''
r_info = ''

q = i.keyword
cl = SphinxClient()
cl.SetServer ( 'localhost', 3312 )
res = cl.Query ( q, 'blog' )
if not res:
e_info = 'query failed: %s' % cl.GetLastError()

e_info = 'WARNING: %s/n' % cl.GetLastWarning()
if res.has_key('words'):

r_info += '/t/'%s/' found %d times in %d documents<br/>' % (info['word'], info['hits'], info['docs'])
if res.has_key('matches'):
n = 1
s_result = '/nMatches:<br/>'
