Search by distance and getting the actual distance

Hi,

I'm trying to use elasticsearch for geo location search. It works fine so
using a filtered query and the geo_distance filter. What I miss in the
search result is the distance between "my location" and each of the results.
Is it possible somehow to add the distance to the result? Can someone give
me an example or point me to some docs how to make it?

regards,
Matthias

I am also interested in this. Can anyone help? Thanks

I look at that posting already, and i am already sorting by _geo_distance
but no actual distance value is returned (using latest 0.9.2)

Then only in once place somewhere on stackoverflow i found that we need to
use script_fields to get distance to the results and i am wondering why in
many places it is mentioned that distance should be in results if you are
sorting by _geo_distance if it is not?! Maybe i am doing something wrong,
but i tested thousand times.

Only way i could get distance is like this:

"fields": [
"_source"
],
"script_fields": {
"distance": {
"params": {
"lat": 56.959942,
"lon": 24.113656
},
"script": "doc['location'].arcDistanceInKm(lat, lon)"
}
}

Take a look at this example: geo_example.sh · GitHub

The value in the "sort" field is the distance:

  "sort" : [ 114.81801790248922 ]

Since in my test case all returned "sort" fields were almost identical
(event if distance is different) i decided sort key is something different,
some value of inner calculations.

So i think there is a bug somewhere with geo-search, so i reported whole
test case to github issues

Because if you look at my test case: Elasticsearch geo search debug · GitHub
You will see that returned "sort" values are almost identical and also
returned sort order is wrong...

Thanks, it is good to know "sort" actually should return distance, let's
hope there is some explanation why problems in my test case appears.

Yeah, it's one of these gotchas that many people run into. When you specify
location as an array, it follows GeoJson format [lon, lat], instead of lat,
lon. So, if you will flip the numbers in _geo_distance sort location, it
will work as expected:

"_geo_distance": {
"location": [
24.113656,
56.959942
],
"order": "asc",
"unit": "km"
}

Wow, thanks. I spent half a day running tests, googling and finally decided
it could be a bug and even reported.
There should be some warning or exclamation marks like "Important notice" on
docs where it mentions format changes :slight_smile: it too easy to mis-read lat, lon
vs lon, lat.

Thanks a lot.

I'll explore how the docs are built and see what i can do. As i already
have all the test data for geo search probably tutorial on geo search could
be a help too. As i did lot of search yesterday, i noticed all the same
questions all around about geo search. As kimchy added support for Latvian
stemming after one day i wrote an issue (which was essential one for us
choosing ES) and released this feature in a week in new version i think i
owe this community some help too :slight_smile:

Heya, the formatting is specified here for example:
Elasticsearch Platform — Find real-time answers at scale | Elastic. Its hard
to find, I know..., and to be honest its confusing (the order) for me as
well, it used to be the other way around, but we changed it to match the
geojson spec.

Hi,

I'm trying to use elasticsearch for geo location search. It works
fine so using a filtered query and the geo_distance filter. What I miss in
the search result is the distance between "my location" and each of the
results. Is it possible somehow to add the distance to the result? Can
someone give me an example or point me to some docs how to make it?

regards,

The problem was not to found the correct guide page, but to notice that in
one place order of arguments differs from usual one (lat,lon, which uses
for storing, also google uses it) so it is very easy to mis-read it.
Yesterday i set up ES docs on ruby, so that i can contribute some guide
updates. Kimchy, do you agree that in place where lat, lon is way around
there should be some visually more noticeable Note element, so that users
really notice these changes? If you agree on that i can do that and
contribute.

Heya, the formatting is specified here for example:
Elasticsearch Platform — Find real-time answers at scale | Elastic. Its
hard to find, I know..., and to be honest its confusing (the order) for me
as well, it used to be the other way around, but we changed it to match the
geojson spec.

choosing ES) and released this feature in a week in new version i think i
owe this community some help too :slight_smile:

Thanks a lot.

Yeah, it's one of these gotchas that many people run into. When you
specify location as an array, it follows GeoJson format [lon, lat], instead
of lat, lon. So, if you will flip the numbers in _geo_distance sort
location, it will work as expected:

"_geo_distance": {
"location": [
24.113656,
56.959942
],
"order": "asc",
"unit": "km"
}

Since in my test case all returned "sort" fields were almost

So i think there is a bug somewhere with geo-search, so i reported
whole test case to github issues
https://github.com/**elasticsearch/elasticsearch/**issues/1885https://github.com/elasticsearch/elasticsearch/issues/1885

Because if you look at my test case: https://gist.github.com/**
2483009 https://gist.github.com/2483009
You will see that returned "sort" values are almost identical and
also returned sort order is wrong...

Thanks, it is good to know "sort" actually should return distance,
let's hope there is some explanation why problems in my test case appears.

why in many places it is mentioned that distance should be in results if
you are sorting by _geo_distance if it is not?! Maybe i am doing something
wrong, but i tested thousand times.

Only way i could get distance is like this:

"fields": [
"_source"

"script_fields": {
"distance": {
"params": {
"lat": 56.959942,

Yes, I definitely agree that it should be noticeable. I thought that it is
(there is a special note in that format).
