To use this, first open your <elasticsearch_dir>/config/elasticsearch.yml file and append the following lines.
http.cors.enabled : true
http.cors.allow-origin : "*"
http.cors.allow-methods : OPTIONS, HEAD, GET, POST, PUT, DELETE
http.cors.allow-headers : X-Requested-With,X-Auth-Token,Content-Type, Content-Length
The above configuration lets ElasticSearch accept cross-origin requests.
Next, launch ElasticSearch with
<elasticsearch_dir>/bin/elasticsearch
Then, load the sample data into the bank index with:
curl -XPOST 'localhost:9200/bank/account/_bulk?pretty&refresh' --data-binary "@accounts.json"
After that, launch a Python web server to serve the index.html file with
# Python 3
python -m http.server
or
# Python 2
python -m SimpleHTTPServer
Finally, navigate to http://localhost:8000 and issue a search (e.g. "Neptune").
