Couchbase N1QL query running, but no data retrieved (wrong query i guess) - join

Question

I am trying to retrieve data from 2 buckets, no error but nothing shows up (I do have documents I need in these buckets).
1st bucket: a_bucket
here is the document I am interested in (I do have 3 different docs)
author_ID document:
{
"author_ID": 1,
"profil_creation_date": "2017/01/01/01:23:05/+5",
"prefix": "Mr.",
"first_name": "Dylan",
"middle_name_s": "Alfred",
"last_name": "Kerr",
"date_of_birth": "1974/01/02",
"sex": "M",
"marital_status": "Single",
"mobile_phone": "[phone]",
"address": [
{
"address_1": {
"address_ID": 1,
"home_address": "338 Counts Lane",
"city": "West Hartford",
"province/state": "CT",
"postal_code": "06105"
}
},
{
"address_2": {
"address_ID": 2,
"work_address": "977 Copperhead Rd",
"city": "Newington",
"province/state": "CT",
"postal_code": "06111"
}
}
]
}
2nd bucket: b_bucket
here are the 2 docs I am interested in:
p_output_ID document:
{
"p_output_ID": 1,
"author_ID": 2,
"overall_score": 4.41,
"status": {
"r_status_first": "TRUE",
"r_status_second": "FALSE",
"r_status_third": "YES",
"y_status_second": "TRUE",
"y_status_third": "FALSE",
"g_status_third": "TRUE"
}
}
timing_ID document:
{
"timing_ID": 1,
"p_output_ID": 1,
"author_ID": 1,
"date_and_time": "2017-06-06/23:45:25.25/+5",
"time_in_seconds": 12525,
"incremental_time_in_seconds": "time_in_seconds",
"current_state_and_duration": {
"state": "RED",
"duration_in_seconds": 33333
}
}
my goal is to grab these informations in one query ():
prefix, first_name, middle_name_s, last_name (from author_ID document in a_bucket)
overall_score (from p_output_ID document in b_bucket)
date_and_time, state (from timing_ID document in b_bucket)
Here is my query:
select p2.current_state_and_duration.state, p1.overall_score, p2.date_and_time
from proc_data_bucket p1 USE KEYS "p_output_ID"
JOIN proc_data_bucket p2 ON KEYS "author_ID";
The syntax is OK, but I am getting no data
Please help me with that...

Answer 1

CREATE INDEX ix1 ON b_bucket(timing_ID);
SELECT p1.prefix, p1.first_name, p1.middle_name_s, p1.last_name,
p2.date_and_time,p2.state,
p3.overall_score
FROM b_bucket p2
JOIN a_bucket p1 ON KEYS ("author_" || TO_STRING(p2.author_ID))
JOIN b_bucket p3 ON KEYS ("p_output_" || TO_STRING(p2.p_output_ID))
WHERE p2.timing_ID BETWEEN 10 AND 50;
