And a comparison to Elasticsearch would be helpful, since ES gets a lot of mileage from their super-easy JSON support. IOW, how much of the ES "advantage" is eliminated.

The simplest use case is to dump the entire json using split=/&f=/** . i am
planning to add an alias for the same (SOLR-6343) .

The nested docs is missing now and we will need to add it. A ticket needs
to be opened

Thanks, Erik, but... I've read that Jira several times over the past
month, it is is far too cryptic for me to make any sense out of what it is
really trying to do. A simpler approach is clearly needed.

My perception of SOLR-6304 is not that it indexes a single JSON object as
a single Solr document, but that it generates a collection of separate
documents, somewhat analogous to Lucene block/child documents, but... not
quite.

I understood the request on this message thread to be the flattening of a
single nested JSON object to a single Solr document.

IMHO, we need to be trying to make Solr more automatic and more
approachable, not an even more complicated "toolkit".

Jack et al - there’s now this, which is available in the any-minute
release of Solr 4.10: https://issues.apache.org/jira/browse/SOLR-6304

 That's a completely different concept, I think - the ability to return a
single field value as a structured JSON object in the "writer", rather than simply "loading" from a nested JSON object and distributing the key values
to normal Solr fields.

See my Jira. It supports it via json.fsuffix=_json&wt=json

Indexing and query of raw JSON would be a valuable addition to Solr, so
maybe you could simply explain more precisely your data model and
transformation rules. For example, when multi-level nesting occurs, what
does your loader do?

Maybe if the fielld names were derived by concatenating the full path of
JSON key names, like titles_json.FR, field_naming nesting could be handled
in a fully automated manner.

I had been thinking of filing a Jira proposing exactly that, so that
even the most deeply nested JSON maps could be supported, although
combinations of arrays and maps would be problematic.

Hello everybody,

I had a requirement to store complicated json documents in solr.

i have modified the JsonLoader to accept complicated json documents with
arrays/objects as values.

It stores the object/array and then flatten it and  indexes the fields.

e.g  basic example document

{
     "titles_json":{"FR":"This is the FR title" , "EN":"This is the EN
title"} ,
     "id": 1000003,
     "guid": "3b2f2998-85ac-4a4e-8867-beb551c0b3c6"
}

It will store titles_json:{"FR":"This is the FR title" , "EN":"This is
the
EN title"}
and then index fields

titles.FR:"This is the FR title"
titles.EN:"This is the EN title"


Do you see any problems with this approach?



Regards,
Michael Pitsounis
