Hi,
I've got index with geo\_shape type field.
I can POST doc via dev\_tool:
For example:
POST test/doc
{
"geo\_link" : {
"type": "LineString",
"coordinates": [
[
-87.623177,
41.881832
],
[
-86.623177,
42.881832
]
]
}
}
But when I try to post records via logstash I've got error: "geo coordinates must be numbers".
Logstash file:
input {...}
filter {
mutate {
add\_field =\> ["[geo\_link][type]", "linestring" ]
add\_field =\> ["[geo\_link][coordinates]",[[-87.623177, 41.881832], [-86.623177, 42.881832]] ]
}
}
output {...}
I tried many combinations of coordination number but I always have the same error.

I have the same problem , how to do indexing correctly a linestring via logstash?

That results in
```
"geo_link" => {
"type" => "linestring",
"coordinates" => [
[0] "[-87.623177, 41.881832]",
[1] "[-86.623177, 42.881832]"
]
},
```
for me. You can split it up
```
add_field => {
"[geo_link][type]" => "linestring"
"[geo_link][coordinates][0]" => [-87.623177, 41.881832]
"[geo_link][coordinates][1]" => [-87.623177, 41.881833]
}
}
```
which results in
```
"geo_link" => {
"type" => "linestring",
"coordinates" => {
"1" => [
[0] "-87.623177",
[1] "41.881833"
],
"0" => [
[0] "-87.623177",
[1] "41.881832"
]
}
},
```
Note that these coordinates are all strings, not numbers. You may need to mutate+convert them.

Thanks for reply.
But now I have message: "coordinates cannot be specified as objects"
I tried:
{
add\_field =\> ["[geo\_link][type]", "linestring" ]
add\_field =\> ["[geo\_link][coordinates][0]", "[-87.623177, 41.881832]" ]
add\_field =\> ["[geo\_link][coordinates][1]", "[-87.623177, 41.881832]" ]
```
convert => { "[geo_link][coordinates][0]" => "float" }
convert => { "[geo_link][coordinates][1]" => "float" }
```
}
I also tried:
add\_field =\> ["[geo\_link][type]", "linestring" ]
add\_field =\> ["[geo\_link][coordinates][0][lat]", " -87.623177" ]
add\_field =\> ["[geo\_link][coordinates][0][lon]", "41.881832" ]
add\_field =\> ["[geo\_link][coordinates][1][lat]", " -87.623177" ]
add\_field =\> ["[geo\_link][coordinates][1][lon]", "41.881832" ]
but the same result.

I cannot see a way to create an array of arrays of floats using mutate. So use ruby
```
mutate {
add_field => {
"[geo_link][type]" => "linestring"
}
}
ruby {
code => '
event.set("[geo_link][coordinates]", [[-87.623171, 41.881832], [-87.623177, 41.881833]])
'
}
```
which results in
```
"geo_link" => {
"type" => "linestring",
"coordinates" => [
[0] [
[0] -87.623171,
[1] 41.881832
],
[1] [
[0] -87.623177,
[1] 41.881833
]
]
},
```
