PBC Yokozuna Index Get
  
  
Retrieve a search index from Riak Search.
Request
The name parameter is the name of the index to fetch as a binary.
message RpbYokozunaIndexGetReq {
    optional bytes name  =  1;
}
Response
If a name is passed through the RpbYokozunaIndexGetReq request, zero
or one index objects are returned. If name is empty, then a list of
all indexes will be returned.
Both requests will return a response of this form.
message RpbYokozunaIndexGetResp {
    repeated RpbYokozunaIndex index  =  1;
}
This message will contain any number of RpbYokozunaIndex messages,
depending on how many indexes are returned.
message RpbYokozunaIndex {
    required bytes name   =  1;
    optional bytes schema =  2;
    optional uint32 n_val =  3;
}
Each message specifying an index must include the index’s name as a
binary (as name). Optionally, you can specify a schema name and/or an n_val, i.e. the number of nodes on which the
index is stored (for GET requests) or on which you wish the index to be
stored (for PUT requests). An index’s n_val must match the associated
bucket’s n_val.
