处理solr的理想方法是使用php?

simplexml solr php

Tom cmoron · 技术社区 · 15 年前

Firslty,我知道这方面有一些类似的问题,但我认为这种情况是不同的,足以证明自己的问题。

我正在运行一个solr索引,通过一个安装在灯服务器上的码头。我目前使用 simplexml_load_file 函数引入搜索结果,然后通过几个函数对其进行解析。我对这个过程很满意,直到我开始遇到一个基本问题。

字段名不能通过simpleXML函数传递。例如,这个结果;

<doc>
  <float name="score">0.73325396</float>
  <str name="add1">Ravensbridge Drive</str>
  <str name="comments">0</str>
  <str name="company">Stratstone Lotus Leicester</str>
  <str name="feed_id"/>
  <str name="id">1711765</str>
  <str name="pcode">LE4 0BX</str>
  <str name="psearch">LE4</str>
  <str name="rating">0</str>
</doc>

在simpleXML对象中会像这样;

 [doc] => Array
 (
   [0] => SimpleXMLElement Object
   (
     [float] => 0.73325396
     [str] => Array
     (
       [0] => Ravensbridge Drive
       [1] => 0
       [2] => Stratstone Lotus Leicester
       [3] => SimpleXMLElement Object
       (
         [@attributes] => Array
         (
           [name] => feed_id
         )
       )
       [4] => 1711765
       [5] => LE4 0BX
       [6] => LE4
       [7] => 0
     )
   )

当找到一个完整的数据集时,数组中存储了11位数据,但是当一些数据丢失时,数据会四处移动,我的解析器就会松脱。

所以,我已经研究了库/类来正确地完成它。也就是说,两个主要的; Apache Solr 和 solr-php-client 但这两个看起来都过于复杂,实际的例子很少,而且它们都不支持不同的solr核心,其中我使用了几个。

最好用什么?我现在被困在这里了,任何帮助都会非常感谢。

谢谢!

当然,使用现有的客户之一。对于多核支持,它与为每个solr实例创建客户机实例一样简单。

Solr扩展功能更强大,但使用起来仍然非常直观。这里有两个示例代码片段,用于进行基本查询并使用这两个库返回结果:

PHP Solr extension

<?php
$options = array
(
    'hostname' => 'localhost',
    'port'     => '8080',
    'path'     => '/solr'
);

$client = new SolrClient($options);

$query = new SolrQuery();
$query->setQuery('fox');
$query->setStart(0);
$query->setRows(50);
// specify which fields do we want to retrieve
$query->addField('id')->addField('title_t')->addField('source_t');

$res = $client->query($query)->getResponse();

// how does he response look like?
var_dump($res);
/*

  public 'responseHeader' => 
    object(SolrObject)[5]
      public 'status' => int 0
      public 'QTime' => int 0
      public 'params' => 
        object(SolrObject)[6]
          public 'fl' => string 'id,title_t,source_t' (length=19)

          1 => 
            object(SolrObject)[9]
              ...
          2 => 
            object(SolrObject)[10]
              ...
          (...)
*/

var_dump($res->reponse->docs[0]);

*/

solr-php-client ( official example of use )

require_once 'library/SolrPhpClient/Apache/Solr/Service.php';

$solr = new Apache_Solr_Service('localhost', '8080', '/solr');

if (!$solr->ping()) {
    exit('Solr service not responding.');
}

$offset = 0;
$limit = 50;

$query = 'fox';
$res = $solr->search($query, $offset, $limit);

// how does he response look like?
var_dump($res->response);

/*
