问题
I am using apache solr for text search. I have nested document structure
. This is one.json
file :
{
"id": "1",
"info": {
"first_name": "John",
"last_name": "Doe",
"gender": "male"
}
}
I created a solr core and posted one.json
in it.Solr indexed and flattened the above document's nested structure
, I guess for better indexing in following form:
{
"id":["1"],
"info.first_name":["John"],
"info.last_name":["Doe"],
"info.gender":["male"]
}
Now, when I make the search query,the result is in flattened form
.
For my requirement, I want the response json in original nested form
.
How can this be achieved in Solr ? Is there some tool that I can use with Solr to get the original nested json
while making search?
Addition:
I am using solr 6.3.0
. When I added the json file to the core, solr automatically indexed the json file
. A managed-schema.xml
was generated by solr.
Here is a portion of managed-schema.xml
where fields are defined:
<field name="_root_" type="string" docValues="false" indexed="true" stored="false"/>
<field name="_text_" type="text_general" multiValued="true" indexed="true" stored="false"/>
<field name="_version_" type="long" indexed="false" stored="false"/>
<field name="id" type="string" multiValued="false" indexed="true" required="true" stored="true"/>
<field name="info.first_name" type="strings"/>
<field name="info.gender" type="strings"/>
<field name="info.last_name" type="strings"/>
回答1:
This may be possible with srcField parameter as described in the Reference Guide section on processing custom JSON. Notice the limitation that your nested document will be indexed as a single document.
The techproduct example has the srcField configured, if you want to test it with a shipped schema.
