Geo_distance query always returns results, regardless of distance, latitude, or longitude

rythem · February 26, 2019, 9:46am

I've been trying out the geo_distance query on the latest version of Elasticsearch (6.6), but it seems I always get hits/results back. If I follow the example here and change either the latitude/longitude to something way off with a distance of 1 km, I'm still getting hits back.

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-geo-distance-query.html

For example, the following query is still returning a result:

GET http://localhost:9200/my_locations/_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "1km",
                    "pin.location" : [30, 0]
                }
            }
        }
    }
}

Is there something obvious I'm missing here??? I've attached the full Elasticsearch build information below

{
  "name" : "PrZXr5l",
  "cluster_name" : "elasticsearch_luke",
  "cluster_uuid" : "VJKApkuYTx6KIfIx3O23Ig",

    "number" : "6.6.1",

    "build_date" : "2019-02-13T17:10:04.160291Z",

What is a typical result you are getting you should not get back?

Could you provide a full recreation script as described in About the Elasticsearch category. It will help to better understand what you are doing. Please, try to keep the example as simple as possible.

A full reproduction script will help readers to understand, reproduce and if needed fix your problem. It will also most likely help to get a faster answer.

David,

Thanks for the fast response! The reproduction script is in your documentation in the link in my previous post... I can copy/paste it here if you'd like though for completeness later on?

I expect to not get any results back if I'm specifying a distance with a latitude/longitude outside of the given data set. As I mentioned in my previous post, if I'm at a longitude/latitude of 30/0 with a 1 kilometer distance, I definitely shouldn't be returning a point back with a latitude of 40.12 and longitude -71.34... that's significantly further away than 1 km...

Copy/pasting Elastic's documentation here for future reference/readers

PUT /my_locations
{
    "mappings": {
        "_doc": {
            "properties": {
                "pin": {
                    "properties": {
                        "location": {
                            "type": "geo_point"
                        }
                    }
                }
            }
        }
    }
}

PUT /my_locations/_doc/1
{
    "pin" : {
        "location" : {
            "lat" : 40.12,
            "lon" : -71.34
        }
    }
}

GET /my_locations/_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "1km",
                    "pin.location" : [30, 0]
                }
            }
        }
    }
}

This is returning a hit when the data point being returned is definitely not within 1 kilometer of longitude 30, latitude 0

I just tried this script (in 7.0.0-beta1 though but I'm going to try in 6.6):

DELETE /my_locations
PUT /my_locations
{
  "mappings": {
    "properties": {
      "pin": {
        "properties": {
          "location": {
            "type": "geo_point"
          }
        }
      }
    }
  }
}

PUT /my_locations/_doc/1
{
    "pin" : {
        "location" : {
            "lat" : 40.12,
            "lon" : -71.34
        }
    }
}

GET /my_locations/_search
{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "1km",
                    "pin.location" : [30, 0]
                }
            }
        }
    }
}

And this gives:

{
  "took" : 104,
  "timed_out" : false,
  "_shards" : {
    "total" : 1,
    "successful" : 1,
    "skipped" : 0,
    "failed" : 0
  },
  "hits" : {
    "total" : {
      "value" : 0,
      "relation" : "eq"
    },
    "max_score" : null,
    "hits" : [ ]
  }
}

dadoonet · February 26, 2019, 5:14pm

Same in 6.6.1. No hits returned.

Are you sure that:

You are running exactly this script?
You are using the latest 6.6.1 version?

rythem · February 27, 2019, 1:53pm

David,

Thank you for the super fast responses! If I try your following script below, I get an error:

PUT /my_locations
{
  "mappings": {
    "properties": {
      "pin": {
        "properties": {
          "location": {
            "type": "geo_point"
          }
        }
      }
    }
  }
}

I noticed yours doesn't have a "_doc" key in the payload for the mappings.. is this a caveat of 7.0.0-beta1 for you? If I try this on 6.6.1 it returns a 400 with the error message:

{
  "error": {
    "root_cause": [
      {
        "type": "mapper_parsing_exception",
        "reason": "Root mapping definition has unsupported parameters:  [pin : {properties={location={type=geo_point}}}]"
      }
    ],
    "type": "mapper_parsing_exception",
    "reason": "Failed to parse mapping [properties]: Root mapping definition has unsupported parameters:  [pin : {properties={location={type=geo_point}}}]",
    "caused_by": {
      "type": "mapper_parsing_exception",
      "reason": "Root mapping definition has unsupported parameters:  [pin : {properties={location={type=geo_point}}}]"
    }
  },
  "status": 400
}

Is there something else off here? I've included the build version higher in this thread. Is there a known issue with that release version?

dadoonet · February 27, 2019, 2:10pm

Yeah. It's because I'm using 7.0 and not 6.x.

You can add _doc in the mapping between mappings and properties and that will work on 6.x

rythem · February 27, 2019, 2:33pm

Okay, then that's verbatim the script I have above and I'm still getting back a response:

Request
GET http://localhost:9200/my_locations/_search

{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "1km",
                    "pin.location" : [30, 0]
                }
            }
        }
    }
}

Response

    },

        "hits": [
            {

            "_type": "_doc",
            "_id": "1",
            "_score": 1,
            "_source": {
                "pin": {
                    "location": {
                        "lat": 40.12,
                        "lon": -71.34
                    }
                }
            }
            }
        ]
    }
}

Are there any additional tweaks/plugins/things I have to have installed in my Elasticsearch instance? I'm trying to figure out what we're doing differently here.

dadoonet · February 27, 2019, 2:47pm

I suspect that you put a blank line in Kibana console between:

GET http://localhost:9200/my_locations/_search

and

{
    "query": {
        "bool" : {
            "must" : {
                "match_all" : {}
            },
            "filter" : {
                "geo_distance" : {
                    "distance" : "1km",
                    "pin.location" : [30, 0]
                }
            }
        }
    }
}

Did you?

Or that you are not running this exact script in Kibana dev console.

rythem · February 27, 2019, 2:57pm

Figured it out! This is an issue with the REST client I'm using (Paw from https://paw.cloud). Apparently, it's stripping out the body on GET requests. When I tried the above with Postman, it sent the payload and got the response correctly. Thanks for the help @dadoonet!!

For other people that hit this problem with Paw, here's how you enable the payload on any request:

dadoonet · February 27, 2019, 3:34pm

You should have tell me from the start.
Actually Kibana transforms GET with body to POST requests as many browsers if not all do not support GET with a body.

rythem · February 27, 2019, 3:44pm

Good to know. Thank you @dadoonet
