Ranged Query with ElasticSearch - elasticsearch

Question

I'm testing with ElasticSearch and I'm having problems with ranged queries.
Consider the following document that I've inserted:
curl -XPUT 'localhost:9200/test/test/test?pretty' -d '
{
"name": "John Doe",
"duration" : "10",
"state" : "unknown"
}'
And now I'me trying to do a ranged query that catches all documents whose duration is between 5 and 15:
curl -XPOST 'localhost:9200/test/_search?pretty' -d '
{
"query": {
"range": {
"duration": {
"gte": "5",
"lte": "15"
}
}
}
}'
This returns no hits however if I run the Query like this:
curl -XPOST 'localhost:9200/test/_search?pretty' -d '
{
"query": {
"range": {
"duration": {
"gte": "10"
}
}
}
}'
It returns the Document I've inserted earlier. How can I query ElasticSearch for documents with the duration value between 5 and 15.

The problem is that you are indexing your values as strings. This causes the range query not to work. Try indexing and querying as follows:
curl -XPUT 'localhost:9200/test/test/test?pretty' -d '
{
"name": "John Doe",
"duration" : 10,
"state" : "unknown"
}'
curl -XPOST 'localhost:9200/test/_search?pretty' -d '
{
"query": {
"range": {
"duration": {
"gte": 5,
"lte": 15
}
}
}
}'
This wil yield the following result:
{
"took" : 2,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 1,
"max_score" : 1.0,
"hits" : [ {
"_index" : "test",
"_type" : "test",
"_id" : "test",
"_score" : 1.0,
"_source":
{
"name": "John Doe",
"duration" : 10,
"state" : "unknown"
}
} ]
}
}
