Noble Paul commented on SOLR-6633:
----------------------------------
I hope you are all clear about the functionality/usecase. If the
API/configuration needs change please suggest .
bq.I'm not clear on this either... my best guess is that it is like a
copyField. And all values (but not keys) are copied into this field?
It is like a copyFIeld but without a src field.
bq.I'm not quite clear on "mapUniqueKeyOnly" either... (what the "Only" refers
to).
All the values are extracted and dumped into a field. But it ensures that a
uniqueKey is created. They don't need to use this attribute at all .
f=text:/**&f=uniqueKeyField:/unique-field-name should do the trick. Then , if
the json does not have a value for uniqueKey it fails.
bq.Oh, and when we have magic field names, the convention in Solr has been an
underscore on both sides
{{_src}} is not a magic field . It is explicitly added to the schema and it is
explicitly specified here as well
> let /update/json/docs store the source json as well

> it is a common requirement to store the entire JSON as a field in Solr.
> we can have a extra param srcField=field_name to specify the field name
> the /update/json/docs is only useful when all the json fields are predefined
> or in schemaless mode.
> The better option would be to store the content in a store only field and
> index the data in another field in other modes
> the relevant section in solrconfig.xml
> {code:xml}
> <initParams path="/update/json/docs">
> <lst name="defaults">
> <!--this ensures that the entire json doc will be stored verbatim into
> one field-->
> <str name="srcField">_src</str>
> <!--This means a the uniqueKeyField will be extracted from the fields
> and
> all fields go into the 'df' field. In this config df is already
> configured to be 'text'
