Why am I not able to query by geolocation in elastic search? - elasticsearch

Question

So I am experimenting with ElasticSearch and this is what I did.
1) Added a geo_point mapping on my index called "test"
curl -XPOST localhost:9200/test -d '{
"mappings" : {
"type1" : {
"_source" : { "enabled" : false },
"properties" : {
"location" : { "type" : "geo_point", "index" : "not_analyzed" }
}
}
}
}'
2) Indexed a document under test:
curl -XPUT 'localhost:9200/test/type1/1?pretty' -d '{
"location" : {
"lat" : 74,
"lon" : 90
}
}'
3) Then wrote a query by geolocation filter like this:
curl -XPOST 'localhost:9200/test2/_search?pretty' -d '{
"filtered" : {
"query" : {
"match_all" : {}
},
"filter" : {
"geo_distance" : {
"distance" : "200km",
"location" : {
"lat" : 40,
"lon" : -70
}
}
}
}
}'
For this I get:
"error" : "SearchPhaseExecutionException[Failed to execute phase
[query], all shards failed; shardFailures
{[QpGEHtdcReeYmt8X2tG26g][test2][0]:
RemoteTransportException[[Jester][inet[/10.58.91.21:9301]][search/phase/query]];
nested: SearchParseException[[test2][0]: from[-1],size[-1]: Parse

Answer 1

First off, in your query (i.e. the 3rd piece of code), localhost:9200/test2/_search?pretty should be localhost:9200/test/_search?pretty, i.e. you're not querying the correct index.
Then your query is simply missing the query keyword (i.e. filtered should be enclosed in a query), it should look like this:
curl -XPOST 'localhost:9200/test/_search?pretty' -d '{
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"geo_distance": {
"distance": "200km",
"location": {
"lat": 40,
"lon": -70
}
}
}
}
}
}
