This adds the ability to index term prefixes into a hidden subfield, enabling prefix queries to be run without multitermquery rewrites. The subfield reuses the analysis chain of its parent text field, appending an EdgeNGramTokenFilter. It can be configured with minimum and maximum ngram lengths. Query terms with lengths outside this min-max range fall back to using prefix queries against the parent text field. The mapping looks like this: "my_text_field" : { "type" : "text", "analyzer" : "english", "index_prefix" : { "min_chars" : 1, "max_chars" : 10 } } Relates to #27049 |

Elasticsearch REST API JSON specification
This repository contains a collection of JSON files which describe the Elasticsearch HTTP API.
Their purpose is to formalize and standardize the API, to facilitate development of libraries and integrations.
Example for the "Create Index" API:
{
"indices.create": {
"documentation": "http://www.elastic.co/guide/en/elasticsearch/reference/master/indices-create-index.html",
"methods": ["PUT", "POST"],
"url": {
"path": "/{index}",
"paths": ["/{index}"],
"parts": {
"index": {
"type" : "string",
"required" : true,
"description" : "The name of the index"
}
},
"params": {
"timeout": {
"type" : "time",
"description" : "Explicit operation timeout"
}
}
},
"body": {
"description" : "The configuration for the index (`settings` and `mappings`)"
}
}
}
The specification contains:
- The name of the API (
indices.create
), which usually corresponds to the client calls - Link to the documentation at http://elastic.co
- List of HTTP methods for the endpoint
- URL specification: path, parts, parameters
- Whether body is allowed for the endpoint or not and its description
The methods
and url.paths
elements list all possible HTTP methods and URLs for the endpoint;
it is the responsibility of the developer to use this information for a sensible API on the target platform.
