使用带有多个索引的PHP的Sphinx

Question

我问过几个类似的问题,但可能没有提供所需的全部信息.

我已经设置了最新版本的Sphinx - 并创建了索引(虽然我不是100%我已经优化了这个配置)(请参阅底部的pastebin链接以获取此配置)

下面是连接到Sphinx API的脚本,其中包含我想要搜索的字符串'teaching' - 目前我有四个索引(请参阅此处的配置 - http://pastebin.com/DGgheqYm)i ' d需要能够确定每个结果来自哪个索引,因为这将确定我需要在哪个表上执行查询

例如..

// {$table}/{$pk} would vary depending on which index we are using (eg if articles index - then it would use the table called 'articles'
$IDs = implode(",",array_keys($result["matches"]));
$sql = "SELECT * FROM {$table} WHERE {$pk} IN ($IDs) ORDER BY FIELD(`id`,$IDs)"

有了它返回的ID数组,任何人都可以建议最好的方法: -

• 确定结果来自哪个索引以确定查询

• 并且..如果我正在做这个'正确的方式' - 与Spinx的一点菜鸟:)

  <?php
  include('api/sphinxapi.php');
  $cl = new SphinxClient();
  $cl->SetServer( "localhost", 9312 );
  $cl->SetMatchMode( SPH_MATCH_ANY  );
  $result = $cl->Query( "teaching" );
  
  if ( $result === false ) {
  echo "Query failed: " . $cl->GetLastError() . ".\n";
  }
  else {
  if ( $cl->GetLastWarning() ) {
    echo "WARNING: " . $cl->GetLastWarning() . "
  ";
  }
  
  if ( ! empty($result["matches"]) ) {
    foreach ( $result["matches"] as $doc => $docinfo ) {
          echo "$doc\n";
    }
  
    print_r( $result );
   }
   }
  
   exit;
   ?>

更新:这里仍有问题是Sphinx API的输出 - 我无法理解为什么我使用Barry的帖子帮助添加的属性似乎没有出现 http://pastebin.com/jzBexCBq

Answer 1

每个索引都设置一个'常量'属性....

source articles
...
sql_query = SELECT ID, 1 AS table_id, Title, Description FROM articles
sql_attr_uint = table_id
...

source publications
...
sql_query = SELECT Title_ID, 2 AS table_id, Title, PageTitle, PageContent, Description FROM publications
sql_attr_uint = table_id
...

//etc

然后

foreach ( $result["matches"] as $doc => $docinfo ) {
    switch($docinfo['attrs']['table_id']) {
        case 1: echo "Article:$doc\n"; break;
        case 2: echo "Publication:$doc\n"; break;
        case 3: echo "Library Content:$doc\n"; break;
        //etc
    }
}
