在搜索过程中无法显示内容字段，即使已使用managedSchemaResourceName中指定的资源中的curl将以下行添加到架构中。
<field name="content" stored="true" type="text_general" indexed="true"/>
我正在使用ManagedIndexSchemaFactory中的架构。
由于ExtractRequestHandler默认情况下已在solrconfig.xml中定义，因此我使用ManagedIndexSchemaFactory。我添加了内容字段行以允许在用户执行查询时显示索引内容，因为默认设置不适用于要显示的内容。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
我使用以下命令索引了该文档：
java -Dc=collection1 -Dauto=true -jar example\exampledocs\post.jar example\exampledcos\solr-word.pdf。
文档已成功编入索引，当我搜索内容中的任何单词时，搜索能够返回文档ID和其他信息，如主题，作者，日期等。但是，文档的内容是没有显示。
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，那就是我得到的：

如果我在fl参数中请求内容字段，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": [
{},
{}
]
}
}
如果我执行q=content:[* TO *]&fl=id,content
{
"responseHeader":{
"status":0,
"QTime":5,
"params":{
"fl":"id,content",
"q":"content:[* TO *]"}},
"response":{"numFound":0,"start":0,"docs":[]
}
}
我能够在Solr 4.10.1中使用它，但它在Solr 5.0中不起作用。对于Solr 5.0，我需要注意哪些内容与以前的Solr版本不同？
答案 0 :(得分：1)
我只使用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“text”类型。例如，如果您有一组字段，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"/>
并且您希望它们可以搜索，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"/>
