Query Exercise

Login into your ElasticSearch sandbox
Make sure elastic search is running:
```
sudo systemctl restart elasticsearch
```

Populate a few orders:

curl -XPOST localhost:9200/orders/_doc/2 \
-H 'content-type: application/json' \
-d '
{
"id": "2", 
"placedOn": "2017-01-01T00:00:00Z", 
"status": "pending"
}'

curl -XPOST localhost:9200/orders/_doc/3 \
-H 'content-type: application/json' \
-d '
{
"id": "3", 
"placedOn": 
"2016-10-01T00:00:00Z", 
"status": "shipped"
}'

curl -XPOST localhost:9200/orders/_doc/4 \
-H 'content-type: application/json' \
-d '
{
"id": "4", 
"placedOn": "2016-01-01T00:00:00Z", 
"status": "received"
}'

Confirm there are some records to search on:

curl 'localhost:9200/orders/_search?pretty=true'

How many documents did you find?
How do you know whether you received all the documents or just the first page of records?
How do you find all the orders that were shipped?
What is the order of the results?
How do you sort results using an arbitrary field?
Pick a couple of options and run your sort query
Reformat your query to use query Uri instead of query Json
You will be asked to present your sort findings to others...
