无法在 Solr 5.0 中显示索引内容

【中文标题】无法在 Solr 5.0 中显示索引内容【英文标题】：Unable to show the indexed content in Solr 5.0 【发布时间】：2015-03-04 05:41:35 【问题描述】：即使在managedSchemaResourceName 中命名的资源中使用 curl 将以下行添加到架构中，在搜索期间也无法显示内容字段。
<field name="content" stored="true" type="text_general" indexed="true"/>
我正在使用来自 ManagedIndexSchemaFactory 的架构。
由于ExtractRequestHandler 已经默认在solrconfig.xml 中定义，我正在使用ManagedIndexSchemaFactory。我添加了内容字段行以允许在用户进行查询时显示索引内容，因为默认设置不显示内容。我使用curl添加如下：
$ curl -X POST -H 'Content-type:application/json' --data-binary '
"update-field" :
"name":"text", "type":"text_general", "stored":true, "indexed":true, "storeOffsetsWithPositions":true
' http://localhost:8983/solr/collection1/schema
我已使用以下命令为文档编制索引：
java -Dc=collection1 -Dauto=true -jar example\exampledocs\post.jar example\exampledcos\solr-word.pdf.
文档已成功索引，当我从内容中搜索任何单词时，搜索能够返回文档 ID 和其他信息，如主题、作者、日期等。但是，文档的内容是未显示。
这是我从结果中得到的。
如果我没有在fl参数中请求内容字段，我得到的是这样的：

如果我请求 fl 参数中的内容字段，这就是我得到的。
"responseHeader":
"status": 0,
"QTime": 1,
"params":
"fl": "content",
"indent": "true",
"q": "*:*",
"_": "1425362147661",
"wt": "json"
,
"response":
"numFound": 2,
"start": 0,
"docs": [
,
]
如果我进行q=content:[* TO *]&fl=id,content 之类的查询
"responseHeader":
"status":0,
"QTime":5,
"params":
"fl":"id,content",
"q":"content:[* TO *]",
"response":"numFound":0,"start":0,"docs":[]
我可以让它在 Solr 4.10.1 中工作，但它在 Solr 5.0 中不起作用。 Solr 5.0 与以前的 Solr 版本有什么不同，我需要注意什么吗？
【问题讨论】：
【参考方案1】：我只使用过 Solr 版本 5 及更高版本，但希望这会有所帮助：为了使字段可搜索，它必须是“文本”类型。例如，如果您有一组字段，例如：
<field name="title" type="text_general" indexed="true" stored="true" multiValued="true"/>
<field name="description" type="text_general" indexed="true" stored="true"/>
<field name="author" type="text_general" indexed="true" stored="true"/>
<field name="keywords" type="text_general" indexed="true" stored="true"/>
<field name="resourcename" type="text_general" indexed="true" stored="true"/>
<field name="url" type="text_general" indexed="true" stored="true"/>
<field name="content_type" type="string" indexed="true" stored="true" multiValued="true"/>
如果您希望它们可搜索，您必须将相应的副本字段添加到文本中。
<copyField source="title" dest="text"/>
<copyField source="author" dest="text"/>
<copyField source="description" dest="text"/>
<copyField source="keywords" dest="text"/>
<copyField source="content" dest="text"/>
<copyField source="content_type" dest="text"/>
<copyField source="resourcename" dest="text"/>
<copyField source="url" dest="text"/>
