Yonik Seeley commented on SOLR-6633:
------------------------------------
bq. _src is not a magic field . It is explicitly added to the schema and it is
explicitly specified here as well
My point was that we currently have field/param names with both leading and
trailing underscores, and field names without. We should probably stick with
that unless we can come up with a common meaning for leading-underscore-only.
And it's still partially magic (even though it's configurable)... it's another
field that the user did not explicitly ask for (and hence I assume the
underscore was a way to avoid clashing with actual user fields).
> 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
