Common options

edit

The following options can be applied to all of the REST APIs.

Pretty Results

edit

When appending ?pretty=true to any request made, the JSON returned will be pretty formatted (use it for debugging only!). Another option is to set format=yaml which will cause the result to be returned in the (sometimes) more readable yaml format.

Human readable output

edit

Statistics are returned in a format suitable for humans (eg "exists_time": "1h" or "size": "1kb") and for computers (eg "exists_time_in_millis": 3600000` or "size_in_bytes": 1024). The human readable values can be turned off by adding ?human=false to the query string. This makes sense when the stats results are being consumed by a monitoring tool, rather than intended for human consumption. The default for the human flag is true. [0.90.4] Added in 0.90.4.

Parameters

edit

Rest parameters (when using HTTP, map to HTTP URL parameters) follow the convention of using underscore casing.

Boolean Values

edit

All REST APIs parameters (both request parameters and JSON body) support providing boolean "false" as the values: false, 0, no and off. All other values are considered "true". Note, this is not related to fields within a document indexed treated as boolean fields.

Number Values

edit

All REST APIs support providing numbered parameters as string on top of supporting the native JSON number types.

Distance Units

edit

Wherever distances need to be specified, such as the distance parameter in the Geo Distance Filter) or the precision parameter in the Geohash Cell Filter, the default unit if none is specified is the meter. Distances can be specified in other units, such as "1km" or "2mi" (2 miles).

The full list of units is listed below:

Mile	`mi` or `miles`
Yard	`yd` or `yards`
Inch	`in` or `inch`
Kilometer	`km` or `kilometers`
Meter	`m` or `meters`
Centimeter	`cm` or `centimeters`
Millimeter	`mm` or `millimeters`

Result Casing

edit

All REST APIs accept the case parameter. When set to camelCase, all field names in the result will be returned in camel casing, otherwise, underscore casing will be used. Note, this does not apply to the source document indexed.

JSONP

edit

All REST APIs accept a callback parameter resulting in a JSONP result.

Request body in query string

edit

For libraries that don’t accept a request body for non-POST requests, you can pass the request body as the source query string parameter instead.
