Simple proof of concept for elasticsearch node.js client
This poc is actually deployed under https://poc-elastic.gridexx.fr
It simply shows how to search Polycode contents with simple request.
Content is a simple json object, really close from the one we use in our project.
ElasticSearch matches query by relevance score (https://www.elastic.co/guide/en/elasticsearch/reference/current/query-filter-context.html#relevance-scores).
In this POC, we use the NAME and the DESCRIPTION fields to search for contents as query parameters :
With those parameters, you can search for contents with the following request:
- GET
https://poc-elastic.gridexx.fr/content?name=react - GET
https://poc-elastic.gridexx.fr/content?description=days
You can also filter contents by author and tags:
- GET
https://poc-elastic.gridexx.fr/content?tags=programming - GET
https://poc-elastic.gridexx.fr/content?author=gridexx
Finally, you can perform for a query matching overall several fields by using the search query parameter. It will match the query against the NAME, DESCRIPTION, AUTHOR and TAGS fields.
- GET
