Yonik Seeley commented on SOLR-6633:
------------------------------------
bq. Finally, I am not clear on what this really means: all fields go into the
'df' . Do we mean, there is a magic copyField or something?
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?
I'm not quite clear on "mapUniqueKeyOnly" either... (what the "Only" refers
to). I guess if it's false, then all the fields in JSON Object are mapped to
Solr fields based on the key in the JSON?
Oh, and when we have magic field names, the convention in Solr has been an
underscore on both sides (or not at all).
So can we use \_src\_ or src of _src please?
> 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
