搜索结果显示没有片段solr drupal

Question

您好，

我有一个drupal 7，带有solr附件模块的apache solr集成模块。我之前从未收到过这样的通知，但我很困惑为什么搜索片段没有显示出来。看一下通知中提到的代码并做了一个print_r（$ snippets），发现变量中的代码片段并没有显示在搜索结果中。这可能是什么原因？

solrconfig.xml中

<requestHandler name="drupal" class="solr.SearchHandler" default="true">
 <lst name="defaults">
   <str name="defType">dismax</str>
   <str name="echoParams">explicit</str>
   <bool name="omitHeader">true</bool>
   <float name="tie">0.01</float>
     <str name="pf">
       content^2.0
     </str>
   <int name="ps">15</int>
   <!-- Abort any searches longer than 4 seconds -->
   <!-- <int name="timeAllowed">4000</int>  -->
   <str name="mm">1</str>
   <str name="q.alt">*:*</str>

   <!-- example highlighter config, enable per-query with hl=true -->
   <str name="hl">true</str>
   <str name="hl.fl">content</str>
   <int name="hl.snippets">1</int>
   <str name="hl.mergeContiguous">true</str>
   <!-- instructs Solr to return the field itself if no query terms are
    found -->
   <str name="f.content.hl.alternateField">teaser</str>
   <str name="f.content.hl.maxAlternateFieldLength">256</str>
   <!-- JS: I wasn't getting good results here... I'm turning off for now
    because I was getting periods (.) by themselves at the beginning of
    snippets and don't feel like debugging anymore.  Without the regex is
    faster too -->
    <!--<str name="f.content.hl.fragmenter">regex</str>--> <!-- defined below -->

  <!-- By default, don't spell check -->
     <str name="spellcheck">false</str>
  <!-- Defaults for the spell checker when used -->
    <str name="spellcheck.onlyMorePopular">false</str>
    <str name="spellcheck.extendedResults">false</str>
    <!--  The number of suggestions to return -->
    <str name="spellcheck.count">1</str>
  </lst>
  <arr name="last-components">
   <str>spellcheck</str>
  </arr>
 </requestHandler>

这是apacheolr_attachments.module中通知的代码

enter code here
function theme_apachesolr_search_snippets__file($vars) {
  $doc = $vars['doc'];
  $snippets = $vars['snippets'];
  $parent_entity_links = array();

   // Retrieve our parent entities. They have been saved as
   // a small serialized entity
 foreach ($doc->zm_parent_entity as $parent_entity_encoded) {
 $parent_entity = (object) drupal_json_decode($parent_entity_encoded);
 $parent_entity_uri = entity_uri($parent_entity->entity_type, $parent_entity);
 $parent_entity_uri['options']['absolute'] = TRUE;
 $parent_label = entity_label($parent_entity->entity_type, $parent_entity);
 $parent_entity_links[] = l($parent_label, $parent_entity_uri['path'],     $parent_entity_uri['options']);
 }

if (module_exists('file')) {
  $file_type = t('!icon @filemime', array('@filemime' => $doc->ss_filemime, '!icon' => theme('file_icon', array('file' => (object) array('filemime' => $doc->ss_filemime)))));
}
else {
   $file_type = t('@filemime', array('@filemime' => $doc->ss_filemime));
}
//print_r($snippets);echo "\n";
return implode(' ... ', $snippets) . '<span>' . $file_type . ' <em>attached to:</em>' .  implode(', ', $parent_entity_links) . '</span>';

}

schema.xml中

<field name="id" type="string" indexed="true" stored="true" required="true" />
<field name="name" type="string" stored="true" indexed="true"/> 
<!-- entity_id is the numeric object ID, e.g. Node ID, File ID -->

<copyField source="label" dest="sort_label"/>

<field name="teaser" type="text" indexed="false" stored="true"/>

<field name="path" type="string" indexed="true" stored="true"/>
<field name="path_alias" type="text" indexed="true" stored="true" termVectors="true" omitNorms="true"/>
<field name="created" type="string" indexed="true" stored="true" termVectors="true"/>
<field name="Question" type="text" indexed="true" stored="true" termVectors="true"/>
<field name="Response" type="text" indexed="true" stored="true" termVectors="true"/>
<field name="Module" type="text" indexed="true" stored="true" termVectors="true"/>
<field name="Meets" type="text" indexed="true" stored="true" termVectors="true"/>
<field name="cat" type="string" indexed="true" stored="true" termVectors="true"/>

有任何建议要删除通知以及显示代码段吗？

Answer 1

我将return implode(' ... ', $snippets)替换为return implode(' ... ', $snippets['content'])，它对我有用。

我无法保证不会出现问题。 值得一试。
