Elasticsearch Index Polygons?

Elastic Stack Elasticsearch
1

So I see the elasticsearch claims to use "GeoJSON" as the format for
indexing... but when I look at the docs.. the same it gives is:

{
"location" : {
"type" : "polygon",
"coordinates" : [
[ [100.0, 0.0], [101.0, 0.0], [101.0, 1.0], [100.0, 1.0], [100.0, 0.0] ]
]
}
}

Doesn't GeoJSON look like this?

{
"type": "Feature",
"properties": {
"name": "Sparkle",
"age": 11
},
geometry: {
"type" : "polygon",
"coordinates" : [[[100.0, 0.0], [101.0,0.0], [101.0, 1.0], [100.0],
[100.0, 0.0]]]
}
}

My question is how do I index polygons in elasticsearch if I want to attach
properties to it? If I wanted to perform a bulk load for example, what does
one document look like that has polygon information that I can perform
geospatial queries on?

Hi,

Will this help you?

Like Jun said,
You need geo shape type.

The problem is, it is very slow to index shapes (except POINT).

I tried with line-strings and it is extremely slow with linestring 10
points long or longer.

It is just killing the CPU.

Can additional, searchable properties fields be added to this? Say I wanted
to do a geosearch by location and by time property?

Is it recommended to shove it into a properties: {} field like geojson? Or
is it supposed to be peer to location or does it not really matter?

You can whatever you want to the index just define your mapping like this:
{
"my_type" : {
"_all" : {
"enabled" : false
},
"properties" : {
"field1" : {
"type" : "double",
"index" : "no"
},
"my_polygon" : {
"tree" : "quadtree",//or geohash here
"type" : "geo_shape"
},
"field2" : {
"type" : "double",
"index" : "no"
}
}
}
}
