only basic searches are working - elasticsearch

Question

I'm playing with curl querying elasticsearch db through my mac console. But I have troubles to execute more complex searches. So far I can query for match_all like this:
curl -XGET 'localhost:9200/products/fashion/_search?pretty' -d'
{
"query" : { "match_all" : {} }
}'
And I receive the following data:
{
"took" : 7,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 915503,
"max_score" : 1.0,
"hits" : [
{
"_index" : "products",
"_type" : "fashion",
"_id" : "57d49ee494efcfdfe0f3abfe",
"_score" : 1.0,
"_source" : {
"doc" : {
"id" : "57d49ee494efcfdfe0f3abfe",
"name" : "Shorts",
"price" : {
"value" : 35
}
}
}
},
...........
}
I don't have problems to request a mapping like this:
curl -XGET 'localhost:9200/products/_mapping/fashion?pretty'
And the result for price is:
.......
"price" : {
"properties" : {
"currency" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
},
"value" : {
"type" : "long"
}
}
},
....
But all my attempts to query with filter on "price.value" did not hit.
curl -XGET 'localhost:9200/products/fashion/_search?pretty' -d'
{
"query" : {
"constant_score" : {
"filter" : {
"term" : {
"price.value" : 35
}
}
}
}
}'
{
"took" : 26,
"timed_out" : false,
"_shards" : {
"total" : 5,
"successful" : 5,
"failed" : 0
},
"hits" : {
"total" : 0,
"max_score" : null,
"hits" : [ ]
}
}
This query I took from elasticsearch guide
I ran out of ideas and examples how to write this query to return what I obviously have in database. As you might noticed I have at least one document with price.value = 35

Answer 1

That's because your price field is within another field named doc, so you need to query doc.price.value like this:
curl -XPOST 'localhost:9200/products/fashion/_search?pretty' -d'
{
"query" : {
"constant_score" : {
"filter" : {
"term" : {
"doc.price.value" : 35
}
}
}
}
}'
