Indexing Solr无法搜索nutch爬网条目，尽管字段被签名为index=true

我正在运行Nutch1.16爬虫实例和Solr版本8.3.0。我已经能够在本地目录中抓取文件，并编辑

nutch site.xml

，从运行

bin/crawl-s url dircrawl 2>和dircrawl.log的文件中提取一些元数据（尽管没有我希望的那么多）。然后，爬网数据通过
bin/nutch index dircrawl/crawdb/-linkdb dircrawl/linkdb/-dir dircrawl/segments/-filter-normalize
发送到Solr，然后通过标签存储和管理条目

现在，从UI运行Solr Admin，我正在尝试搜索数据。我确保所有我感兴趣的条目都以
index=true
的形式签名。但是，运行除
*：*
以外的任何搜索都将返回零结果。我尝试了所有可能的搜索字段组合，也没有骰子。我将链接到配置文件的描述，首先是solr，然后是nutch

运行任何其他类型查询的响应：

您必须设置要搜索的字段-除非您选择。在较旧版本的schema.xml中，可以为schema配置此选项，但推荐的方法是在查询本身中配置它

但是，要支持自由文本搜索，最好使用
edismax
查询解析器，提供
defType=edismax
，然后通过
qf
（查询字段）参数设置要搜索的字段

q=Bumblebee&qf=title&defType=edismax

。。将在
标题
字段中搜索大黄蜂。您还可以为
qf
指定多个字段名，还可以调整为每个字段指定的权重：

qf=title^10 content

。。它将在
标题
和
内容
中搜索，并且与
内容
字段中的点击相比，
标题
字段中的任何点击的权重要高出十倍

fl
（字段列表）参数调整响应中返回的字段，如果您只需要可用字段的一小部分（例如仅id），则此参数非常有用为了避免更大的响应，并且必须为每个返回的文档从磁盘加载所有字段值。
在搜索
bumblebee
时，您希望返回什么文档？在使用Lucene查询解析器时，通常应该提供字段名，即
fieldname:bumblebee
。如果要使用纯文本搜索，请在查询中附加
defType=edismax&qf=fieldname\u to\u search\u，以使用edismax查询解析器。我正在尝试检索nutch爬网后索引的mp3文件的元数据描述。我已经更新了问题，以包括文件的外观。我已经向solr发送了一个POST命令，将“title”更改为索引。我确保该字段全部更新（我知道过账到solr会替换整个字段），但它仍然不允许我搜索“集合中的每个文档”以外的任何内容。
qf
是您要查询的字段。因此，在第一个示例中，您必须添加
qf=title
以在title字段中进行搜索。在另外两个示例中，您尝试搜索名为
Bumblebee
-的字段，而不进行查询
qf
代表“查询字段”-即要查询的字段。否，
fl
用于设置响应中返回的字段-而不是正在搜索的字段。原因可能是有一条规则可以将所有内容复制到后台的公共字段中，默认模式中的公共字段是
\u text
。然后，默认情况下，该字段也被配置为lucene查询解析器的默认搜索字段。但是，当您使用其他架构时，默认架构中的这些设置将不再存在。部分匹配将取决于您要查询的字段的字段类型。如果是
text\u general
，则只返回与单词匹配的内容。如果是
text\u ngram
或任何其他带有ngram的默认类型（如果您使用的是默认模式-这些内容在每个用例的模式中定义），您也会得到部分命中。
q=Bumblebee&qf=title&defType=edismax

qf=title^10 content
