Sphinx PHP搜索

Question

我正在进行狮身人面像搜索,但却出现了一些非常奇怪的结果.任何帮助表示赞赏.

所以,例如,如果我输入"50",我得到:

• 50分
• 50狮子会
• 50英尺波浪等

这很棒,但是当我搜索"50 Ce"时,我得到:

• RycząceDwudziestki
• Spisek
• 伯恩哈德加尔
• Cowabunga Go-Go

和其他疯狂的结果.此外,当我搜索"50 Cent"时,正确的结果位于顶部,但随后是随机结果.有什么想法吗？

PHP代码:

$query = $_GET['query'];

if (!empty($query))
{
 $sphinx->SetMatchMode(SPH_MATCH_ALL);
 $sphinx->AddQuery($query, 'artists');
 $sphinx->AddQuery($query, 'variations');

 $sphinx->SetFilter('name', array(3));

 $sphinx->SetLimits(0, 10);

 $result = $sphinx->RunQueries();

 echo '<pre>';

 switch ($result)
 {
  case false:
   echo 'Query failed: ' . $sphinx->GetLastError() . "\n";
   break;
  default:
   if ($sphinx->GetLastWarning())
   {
    echo 'WARNING: ' . $sphinx->GetLastWarning() . "\n";
   }

   if (is_array($result[0]['matches']) && count($result[0]['matches']))
   {
    foreach ($result[0]['matches'] as $value => $info)
    {
     $artist = artistDetails($value);
     echo $artist['name'] . "\n";
    }
   }
 }
}

狮身人面像指数和来源:

source artists
{
 type     = mysql

 sql_host    = localhost
 sql_user    = user
 sql_pass    = pass
 sql_db     = db
 sql_port    = 3300

 sql_query    = \
  SELECT \
    id, name \
  FROM artists;

 #UNIX_TIMESTAMP(time)
 #sql_attr_uint   = group_id
 #sql_attr_timestamp  = time

 sql_query_info   = SELECT id,name FROM artists WHERE id=$id
}

index artists
{
 source     = artists
 path     = /var/sphinx/artists
 docinfo     = extern
 charset_type   = utf-8
}

您需要使用min_prefix_len索引配置选项告诉sphinx您希望它对部分单词进行索引和匹配.您可能还需要将enable_star设置为1

http://www.sphinxsearch.com/docs/current.html#conf-min-prefix-len

index artists
{
 source     = artists
 path     = /var/sphinx/artists
 docinfo     = extern
 charset_type   = utf-8
 min_prefix_len   = 2
 enable_star   = 1
}

启用前缀索引后,您将能够搜索"50 Ce*"之类的内容以获得部分单词匹配.如果您希望允许部分单词匹配而不要求用户知道添加*本身,则可能必须以编程方式修改搜索字符串,然后再将其传递给sphinx.
