我正在使用一个名为 solr-php-client (http://code.google.com/p/solr-php-client/) 的 PHP 库与我的 Solr 服务器进行交互。我可以从文档中提取数据、存储它并在其上搜索,但我似乎无法让它允许我将自己的数据添加到索引参数中:

$aParams = array
(
    "literal.ClassName_ms" => "File",
    "literal.SS_ID_i" => 73,
    "literal.Name_ms" => "OverviewOfBenefits.pdf",
    "literal.title" => "Overview Of Benefits",
    "literal.Created_dt" => "2011-09-19T13:50:30Z",
    "literal.last_modified_dt" => "2011-10-12T19:33:59Z",
    "literal.SS_Stage_ms" => "Live",
    "literal.ClassNameHierarchy_ms" => array("Object","ViewableData","DataObject","File"),
    "literal.id" => "File_73_Live",
    "fmap.content" => "text",
);

try {

    $oResponse = $oSOLR->extract($sFilePath, $aParams);
    $oSOLR->commit();
    $oSOLR->optimize();

}
catch(Exception $e) {
    var_dump($e);
}

我可以查询“文本”并获得结果:

<?xml version="1.0" encoding="UTF-8"?>
<response>

<lst name="responseHeader">
 <int name="status">0</int>
 <int name="QTime">0</int>
 <lst name="params">
  <str name="indent">on</str>
  <str name="start">0</str>
  <str name="q">text:Overview</str>
  <str name="rows">10</str>
  <str name="version">2.2</str>
 </lst>
</lst>
<result name="response" numFound="1" start="0">
 <doc>
  <arr name="content_type"><str>application/pdf</str></arr>
  <str name="id">File_73_Live</str>
  <date name="last_modified">2011-02-07T16:21:10Z</date>
 </doc>
</result>
</response>

但我无法查询任何动态字段,即“SS_Stage_ms”:

<?xml version="1.0" encoding="UTF-8"?>
<response>

<lst name="responseHeader">
 <int name="status">0</int>
 <int name="QTime">0</int>
 <lst name="params">
  <str name="indent">on</str>
  <str name="start">0</str>
  <str name="q">SS_Stage_ms:Live</str>
  <str name="rows">10</str>
  <str name="version">2.2</str>
 </lst>
</lst>
<result name="response" numFound="0" start="0"/>
</response>

以下是适用的架构定义:

<field name="id" type="string" indexed="true" stored="true" required="true" /> 
<field name="title" type="text" indexed="true" stored="true" multiValued="true"/>
<field name="text" type="text" indexed="true" stored="false" multiValued="true"/>
<dynamicField name="*_i"  type="int"    indexed="true"  stored="false"/>
<dynamicField name="*_ms"  type="string"  indexed="true"  stored="false" multiValued="true"/>
<dynamicField name="*_dt" type="date"    indexed="true"  stored="false"/>

我切换了模式定义来存储数据,这样我就可以看到 Solr 是如何解释这些字段的:

<field name="id" type="string" indexed="true" stored="true" required="true" /> 
<field name="title" type="text" indexed="true" stored="true" multiValued="true"/>
<field name="text" type="text" indexed="true" stored="true" multiValued="true"/>
<dynamicField name="*_i"  type="int"    indexed="true"  stored="true"/>
<dynamicField name="*_ms"  type="string"  indexed="true"  stored="true" multiValued="true"/>
<dynamicField name="*_dt" type="date"    indexed="true"  stored="true"/>

完成此操作后,我发现所有字段都切换为小写。我找到了答案(http://wiki.apache.org/solr/ExtractingRequestHandler):

lowernames=true|false - 将所有字段名称映射为带下划线的小写。例如,Content-Type 将映射到 content_type。

默认情况下,“lowernames”设置为 true。我在参数中添加了“lowernames”,将其设置为 false,瞧,它起作用了!
