Riak Search 2 not indexing bucket

I'm using Riak as a key-value store backend for a graph database implemented in Python.

I created a custom search schema named nodes. I created and activated a bucket type nodes with the search_index property set to nodes and the datatype property set to map.

I inserted the following data into the bucket default (with bucket type nodes):

key: node1
value: {
    "type_set": {"n1"},
    "foo_set": {"bar", "baz"}
}

NB: the data is automatically transformed into a Map datatype.

I can fetch the data correctly, but I tried the following fulltext searches and no document is returned:

type_set:n1
type_set:*n1*
type_set:*
foo_set:*
_yz_rk:node1
_yz_rk:*

It seems that my document is not indexed.

I also tried to set the search_type property to nodes on the bucket default, but I got the same result.

The parameter search is set to on in the configuration file (/etc/riak/riak.conf) and the OpenJDK 7 is installed.

I have no idea what I'm doing wrong, if anyone can help me, thanks in advance.

First, you should take into account that Riak automatically adds suffix _set, so that you don't have to name yours type_set but type. Otherwise you will have to query for type_set_set:* instead of type_set:*.

Second, according to Data Type Schemas, embedded schemas (as opposed to top-level ones) must use dynamic fields. Apparently Riak prepends field names with some internal identifier of the top-level map. Unfortunately, this also means that you cannot index one set without indexing the other as well.

I've run some tests and found out that <dynamicField name="*_set" type="string" indexed="true" stored="true" multiValued="true"/> works fine, while <dynamicField name="*type_set" type="string" indexed="true" stored="true" multiValued="true"/> does not.
