=== Geo Bounding Box Query
|
|
|
|
A query allowing to filter hits based on a point location using a
|
|
bounding box. Assuming the following indexed document:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
{
|
|
"pin" : {
|
|
"location" : {
|
|
"lat" : 40.12,
|
|
"lon" : -71.34
|
|
}
|
|
}
|
|
}
|
|
--------------------------------------------------
|
|
|
|
Then the following simple query can be executed with a
|
|
`geo_bounding_box` filter:
|
|
|
|
[source,js]
|
|
--------------------------------------------------
|
|
{
|
|
"bool" : {
|
|
"must" : {
|
|
"match_all" : {}
|
|
},
|
|
"filter" : {
|
|
"geo_bounding_box" : {
|
|
"pin.location" : {
|
|
"top_left" : {
|
|
"lat" : 40.73,
|
|
"lon" : -74.1
|
|
},
|
|
"bottom_right" : {
|
|
"lat" : 40.01,
|
|
"lon" : -71.12
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}
|
|
}

==== Query Options
|
|
|
|
[cols="<,<",options="header",]
|
|
|=======================================================================
|
|
|Option |Description
|
|
|`_name` |Optional name field to identify the filter
|
|
|
|
|`coerce` |Set to `true` to normalize longitude and latitude values to a
|
|
standard -180:180 / -90:90 coordinate system. (default is `false`).
|
|
|
|
|`ignore_malformed` |Set to `true` to
|
|
accept geo points with invalid latitude or longitude (default is `false`).
|
|
|
|
|`type` |Set to one of `indexed` or `memory` to defines whether this filter will
|
|
be executed in memory or indexed. See <<geo-bbox-type,Type>> below for further details
|
|
Default is `memory`.
|
|

|

|
|
==== Accepted Formats
|
|
|
|
In much the same way the geo_point type can accept different
|
|
representation of the geo point, the filter can accept it as well:

|
==== Vertices
|
|
|
|
The vertices of the bounding box can either be set by `top_left` and
|
|
`bottom_right` or by `top_right` and `bottom_left` parameters. More
|
|
over the names `topLeft`, `bottomRight`, `topRight` and `bottomLeft`
|
|
are supported. Instead of setting the values pairwise, one can use
|
|
the simple names `top`, `left`, `bottom` and `right` to set the
|
|
values separately.
|
|
|

"must" : {

"match_all" : {}

|
},
|
|
"filter" : {
|
|
"geo_bounding_box" : {
|
|
"pin.location" : {
|
|
"top" : -74.1,
|
|
"left" : 40.73,
|
|
"bottom" : -71.12,

--------------------------------------------------

[float]
|
|
==== geo_point Type
|
|
|
|
The filter *requires* the `geo_point` type to be set on the relevant
|
|
field.
|
|
|
|
[float]
|
|
==== Multi Location Per Document
|
|
|
|
The filter can work with multiple locations / points per document. Once
|
|
a single location / point matches the filter, the document will be
|
|
included in the filter
|
|
|
|
[float]
|
|
[[geo-bbox-type]]
|
|
==== Type
|
|
|
|
The type of the bounding box execution by default is set to `memory`,
|
|
which means in memory checks if the doc falls within the bounding box
|
|
range. In some cases, an `indexed` option will perform faster (but note
|
|
that the `geo_point` type must have lat and lon indexed in this case).
|
|
Note, when using the indexed option, multi locations per document field
|
|
are not supported. Here is an example:
|
|
|
|

{
|
|
"bool" : {
|
|
"must" : {

|
"match_all" : {}
|
|
},
|
|
"filter" : {
|
|
"geo_bounding_box" : {
|
|
"pin.location" : {
|
|
"top_left" : {
|
|
"lat" : 40.73,
|
|
"lon" : -74.1
|
|
},
|
|
"bottom_right" : {
|
|
"lat" : 40.10,
|
|
"lon" : -71.12
|
|
}
|
|
},
|
|
"type" : "indexed"
|
|
}
|
|
}
|
|
}
