QueryParsingException[[mobapp] failed to find geo_point field [location.position] - elasticsearch

Question

I created index using:
curl -XPUT localhost:9200/mobapp -d '{
"mappings": {
"publish_messages": {
"properties": {
"title": {
"type": "string"
},
"location": {
"type": "nested",
"position": {
"type": "geo_point"
},
"name": {
"type": "string"
},
"state": {
"type": "string"
},
"country": {
"type": "string"
},
"city": {
"type": "integer"
}
},
"time": {
"type": "date",
"format": "dd-MM-YYYY"
}
}
}
}
}'
I have this index
"hits": [
{
"_index": "mobapp",
"_type": "publish_messages",
"_id": "184123e0-6123-11e5-83d5-7bdc2a9aa3c7",
"_score": 1,
"_source": {
"title": "Kolkata rocka",
"tags": [
"Tag5",
"Tag4"
],
"date": "2015-09-22T12:11:46.335Z",
"location": {
"position": {
"lat": 11.81776,
"lon": 10.9376
},
"country": "India",
"locality": "Bengaluru",
"sublocality_level_1": "Koramangala"
}
}
}
]
I am trying to do this query:
FilterBuilder filter = geoDistanceFilter("location")
.point(lat, lon)
.distance(distanceRangeInkm, DistanceUnit.KILOMETERS)
.optimizeBbox("memory")
.geoDistance(GeoDistance.ARC);
FilterBuilder boolFilter = boolFilter()
.must(termFilter("tags", tag))
.must(filter);
GeoDistanceSortBuilder geoSort = SortBuilders.geoDistanceSort("location").point(lat, lon).order(SortOrder.ASC);
SearchResponse searchResponse
= client.prepareSearch(AppConstants.ES_INDEX)
.setTypes("publish_messages")
.addSort("time", SortOrder.DESC)
.addSort(geoSort)
.setSearchType(SearchType.DFS_QUERY_THEN_FETCH)
.setPostFilter(boolFilter)
.setFrom(startPage).setSize(AppConstants.DEFAULT_PAGINATION_SIZE)
.execute()
.actionGet();
I am getting QueryParsingException[[mobapp] failed to find geo_point field [location.position]]; }

If you only want to keep your location data together, you don't need to use the nested type, simply use a normal object type (i.e. the default), like this:
curl -XPUT localhost:9200/mobapp -d '{
"mappings": {
"publish_messages": {
"properties": {
"title": {
"type": "string"
},
"location": {
"type": "object", <--- use object here
"properties": { <--- and don't forget properties here
"position": {
"type": "geo_point"
},
"name": {
"type": "string"
},
"state": {
"type": "string"
},
"country": {
"type": "string"
},
"city": {
"type": "integer"
}
}
},
"time": {
"type": "date",
"format": "dd-MM-YYYY"
}
}
}
}
}'
Note that you first need to wipe out your current index using curl -XDELETE localhost:9200/mobapp and then recreate it with the above command and reindex your data. Your query should work afterwards.
