Re: Nested objects and map in Solr
I found the answer to my problems:
1. If you have sub-objects add content_type: your_own_name, to the parent
object, e.g.
{
“name_s” : ”mine”,
content_type: “surnames”,
values {
“surname1” : “first”,
“surname2” : “second
}
}
2. Solr is very picky and will not index an object if it is not well construct
(case of Json) or any of the object's fields don’t comply with their own type.
Particularly I found it with the date/time, one of the valid formats is
-MM-ddTHH:mm:ssZ, e.g. 2015-06-23T13:30:20Z
Hope this help someone else

Some of my objects are not fully indexed. I have 121 objects with sub-objects
and when querying with “*:*” only 81 are found. The objects are in Json
format. I use Solr from within Riak.

Join is the Solr approach to nested documents.
Block join and Query time join are 2 different strategies with different
pros and cons .
Basically :
Block Join :
- force you to follow a specific indexing strategy
- if you want to update a child you need to update the whole block ( parent
+children)
+ 4-5 times faster then query time join
Query Time Join
+ you can index the data how you want, even in different cores
+ you can update single children
- it is slow
What do you mean with strange indexes ?

I have looked at the join but the problem isn’t with the query but on
indexing sub-objects (in some places called also nested objects). The best
documentation I have seen is http://yonik.com/solr-4-8-features/
but I am still getting very estrange indexes when I play with this
approach and others.

This is what you are looking for.
Anyway, this request points out that the documentation is not good enough
to address people to Nested Objects problems.
Maybe this should highlight the need of improving that part of the
documentation.

Dear all,
I am starting with Solr and I cannot index map(key,values) or nested
objects in Solr. I have not been able to find a satisfactory answer online.
Please could anyone let me know where to find the full documentation of how
to index nested objects in Solr? Also how to index and reference in the
search melees in a map?
Example Json:
{name_s:Lion-o, age_i:30, leader_b:true, data:{name:me,
surname:other}, values_ss:[red, blue”]}
{name_s:Cheetara, age_i:28, leader_b:false, content_type:
parentDocument,
_childDocuments_:[{name:1},{name:2},{name:3}]}
What about with:
{name_s:Lion-o, age_i:30, leader_b:true, data:{name”:[“me”],
surname”:[“other”, “next]}, values_ss:[red, blue”]}
I look forward to hearing form you soon.
Thank you in advance,
Amadeo
