indexing - Solr 结果分组错误。字段 'vendor' 的意外文档值类型 SORTED_SET(预期=排序)

Question

我有一个这样的 solr 模式

<fields>
   <field name="id" type="string" indexed="false" stored="true" required="true" />  
   <field name="product" type="string" indexed="true" stored="true" required="true" /> 
   <field name="vendor" type="string" indexed="true" stored="true" required="true" /> 
   <field name="language" type="string" indexed="true" stored="true" required="true" /> 
   <field name="TotalInvoices" type="float" indexed="true" stored="true" required="true"/> 
</fields>   

我正在查询模式，结果是这样的

product,Vendor,Invoice
abc,vendor1,49206.75999999998
abc,vendor2,35654.98000000001
abc,vendor2,94861.25999999998
abc,vendor3,990.9600000000012
abc,vendor3,990.9600000000012
abc,vendor3,990.960000000001

我想按供应商字段对结果进行分组，所以我发布了这样的查询

http://localhost:8983/solr/gettingstarted_shard2_replica2/select?q=abc
&fl=product%2Cvendor%2CTotalInvoices
&wt=json
&indent=true
&debugQuery=true
&group=true
&group.field=vendor

我在调试字段中收到一个错误。

请帮帮我。

Answer 1

我在尝试对“ViewCount”字段进行排序时遇到了同样的问题:

 unexpected docvalues type SORTED_SET for field 'ViewCount' (expected=SORTED) ...

错误理解: 来自 here

Any Trie* numeric fields, date fields and EnumField.`enter code here`
If the field is single-valued (i.e., multi-valued is false), Lucene will use the NUMERIC type.
If the field is multi-valued, Lucene will use the SORTED_SET type. 

看起来错误是由字段“ViewCount”的“多值”属性引起的。此外，作为 doc ，该字段的“索引”属性必须为真。

我有一个核心名称“bigdata”。

我的解决方案:

• 删除“bigdata”中的所有文档

  curl http://localhost:8983/solr/bigdata/update --data ':' -H '内容类型:文本/xml；字符集=utf-8' curl http://localhost:8983/solr/bigdata/update --data '' -H '内容类型:文本/xml； charset=utf-8'

• 将字段更改为 long(或任何非多值类型)并建立索引

  curl -X POST -H 'Content-type:application/json' --data-binary '{ “替换字段”:{ “名称”:“查看次数”， “类型”:“长”， “多值”:假， “索引”:真实的， “存储”:真 } }' http://localhost:8983/solr/bigdata/schema

• 重新加载“大数据”

  http://localhost:8983/solr/admin/cores?action=RELOAD&core=bigdata

• 再次将您的数据导入“大数据”

• 重新加载“大数据”

  http://localhost:8983/solr/admin/cores?action=RELOAD&core=bigdata

问题 1:删除所有文档可能对某些人来说很痛苦。我在没有删除并重新导入所有文档的情况下尝试了上述步骤，但没有奏效。看起来这就是 Crypt 所经历的。

问题 2:如果您使用 seamless mode .我的意思是您不手动编辑模式，您需要在重新导入数据之前在“solrconfig.xml”中设置模式不可变。相关文件是here
