问题描述
我正在尝试使用类似于以下内容的文档配置执行完全导入:
I'm trying to perform a full-import with document configuration similar to the following:
<document>
<entity name="parent" query="select * from parent_table" >
<field name="id" column="ID" />
<entity name="child" query="select * from child_table where PARENT_ID = ${parent.ID}" transformer="ClobTransformer" >
<field name="${child.FIELD_COLUMN}" column="VALUE_COLUMN" clob="true" />
</entity>
</entity>
</document>
假设来自parent.ID的child_table的字段/值结果= 1看起来像这样:
Let's say the field/value results from the child_table for parent.ID=1 look like this:
FIELD_COLUMN VALUE_COLUMN
fieldA value1
fieldB value2
fieldB value3
fieldA和fieldB的架构配置(注意fieldB是多值的):
And the schema configuration for fieldA and fieldB (note that fieldB is multivalued):
<field name="fieldA" type="string" indexed="true" stored="true" multiValued="false"/>
<field name="fieldB" type="string" indexed="true" stored="true" multiValued="true" />
运行完全导入后,父1的文档如下所示:
After running full-import, the document for parent 1 looks like this:
{"id":1,
"fieldA":"value1",
"fieldB":["value2"]}
但是,我需要(并且期待)它看起来像这样(fieldB应该有多个)价值):
But, I need (and was expecting) it to look like this instead (fieldB should have multiple values):
{"id":1,
"fieldA":"value1",
"fieldB":["value2","value3"]}
任何帮助将不胜感激!!谢谢!

推荐答案
这是DataImportHandler中的一个错误,它固定为(尚未发布)Solr 4.1。 。
This is a bug in DataImportHandler and it is fixed for (yet to be released) Solr 4.1. See the JIRA issue you opened on this .
