What's wrong with this Elastic query - elasticsearch

Why this query works fine (returns the proper result):
{
"filter": {
"term": { "id": "123456" }
}
}
and this one does not (returns HTTP 500):
{
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"term": { "id": "123456" }
}
}
}
?

Elasticsearch expects query element on the root level similar to the "filter" element. Try this:
{
"query": {
"filtered": {
"query": {
"match_all": {}
},
"filter": {
"term": { "id": "123456" }
}
}
}
}

elastic exists query for nested documents

I have a nested documents as:
"someField": "hello",
"users": [
{
"name": "John",
"surname": "Doe",
"age": 2
}
]
according to this https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-exists-query.html, the above should match:
GET /_search
{
"query": {
"exists" : { "field" : "users" }
}
}
whereas the following should not,
"someField": "hello",
"users": []
but unfortunately both do not match. any ideas?
The example mentioned on the Elasticsearch blog refers to string and array of string types, not for nested types.
The following query should work for you:
{
"query": {
"nested": {
"path": "users",
"query": {
"bool": {
"must": [
{
"exists": {
"field": "users"
}
}
]
}
}
}
}
}
Also, you can refer to this issue for more info, which discusses this usage pattern.
This works for me
GET /type/_search?pretty=true
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "outcome",
"query": {
"exists": {
"field": "outcome.outcomeName"
}
}
}
}
]
}
}
}
With the following index mapping:
{
"index_name": {
"mappings": {
"object_name": {
"dynamic": "strict",
"properties": {
"nested_field_name": {
"type": "nested",
"properties": {
"some_property": {
"type": "keyword"
}
}
}
}
}
}
}
}
I needed to use this query:
GET /index_name/_search
{
"query": {
"nested": {
"path": "nested_field_name",
"query": {
"bool": {
"must": [
{
"exists": {
"field": "nested_field_name.some_property"
}
}
]
}
}
}
}
}
Elasticsearch version 5.4.3
The answer from user3775217 has worked for me but I needed to tweak it to work as expected for must_not. Essentially the bool/must needed to be wrapped around the nested portion of the query:
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "users",
"query": {
"exists": {
"field": "users"
}
}
}
}
}
]
}
}

How to combine term filters with a missing filter in Elasticsearch?

We are using Elasticsearch 1.6 and I have a working three term query that I need to modify with a stand alone working missing filter. Here is the current code:
The original term query with three entries
GET ...
{
"query": {
"nested": {
"path": "MAIN_FIELD",
"query": {
"bool": {
"must": [
{
"term": {
"MAIN_FIELD.ID": 1234
}
},
{
"term": {
"MAIN_FIELD.OTHER_IND": "false"
}
},
{
"term": {
"MAIN_FIELD.INDICATOR": "Y"
}
}
]
}
}
}
}
}
The stand alone missing query:
GET ...
{
"query" : {
"filtered" : {
"filter" : {
"missing" : { "field" : "MAIN_FIELD.OTHER_IND" }
}
}
}
}
How do I change the term query from the first query:
"term": {
"MAIN_FIELD.OTHER_IND": "false"
}
to use a missing filter?
I think what you want is below:
{
"query": {
"nested": {
"path": "MAIN_FIELD",
"query": {
"bool": {
"must": [
{
"term": {
"MAIN_FIELD.ID": 1234
}
},
{
"filtered": {
"filter": {
"missing": {
"field": "MAIN_FIELD.OTHER_IND"
}
}
}
},
{
"term": {
"MAIN_FIELD.INDICATOR": "Y"
}
}
]
}
}
}
}
}

Combine Elastic Search Queries

I have the following 2 queries:
GET places/_search
{
"query": {
"filtered": {
"filter": {
"bool": {
"should": [
{
"term": {
"approved": false
}
}
]
}
}
}
}
}
GET places/_search
{
"query": {
"filtered": {
"filter": {
"geo_bounding_box": {
"loc": {
"top_left": "54.6152065515344, -6.09334913041994",
"bottom_right": "54.5754258987271, -5.76633420732423"
}
}
}
}
}
}
Both work fine, however I am having issues combining the queries and was wondering if anyone could help. Basically I want to retuen all items within the bounding box specified, where the "approved" property is false.
You can keep your filtered query and merge both conditions simply like this inside in a bool/mustfilter
curl -XPOST localhost:9200/places/_search -d '{
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"term": {
"approved": false
}
},
{
"geo_bounding_box": {
"loc": {
"top_left": "54.6152065515344, -6.09334913041994",
"bottom_right": "54.5754258987271, -5.76633420732423"
}
}
}
]
}
}
}
}
}'

ElasticSearch query - exists but doesn't contain

I'm trying to build a query that will return results only if they contain a certain field BUT only if that fields doesn't equal a specific value.
I can't manage the proper syntax:
POST webdata/interaction/_search
{
"query": {
"filtered": {
"filter": {
"exists": {
"field": "mediaType"
},
"and": {
"not" {
"term" : { "mediaType" : "none" }
}
}
}
}
}
}
Use the Bool Filter with must and must_not clauses.
{
"query": {
"filtered": {
"filter": {
"bool": {
"must": {
"exists": {
"field": "mediaType"
}
},
"must_not": {
"term": {
"mediaType": "none"
}
}
}
}
}
}
}

ElasticSeach query not return results

I got 2 querys, the different between them is just 1 filter term.
The first query:
GET _search
{
"query": {
"filtered": {
"query": {
"query_string": {
"query": "*"
}
},
"filter": {
"and": {
"filters": [
{
"term": {
"type": "log"
}
},
{
"term": {
"context.blueprint_id": "adv1"
}
},
{
"term": {
"context.deployment_id": "deploy1"
}
}
]
}
}
}
}
}
return this result:
{
"_source": {
"level": "info",
"timestamp": "2014-03-24 10:12:41.925680",
"message_code": null,
"context": {
"blueprint_id": "Adv1",
"execution_id": "27efcba7-3a60-4270-bbe2-9f17d602dcef",
"deployment_id": "deploy1"
},
"type": "log",
"#version": "1",
"#timestamp": "2014-03-24T10:12:41.927Z"
}
}
The second query is:
{
"query": {
"filtered": {
"query": {
"query_string": {
"query": "*"
}
},
"filter": {
"and": {
"filters": [
{
"term": {
"type": "log"
}
},
{
"term": {
"context.blueprint_id": "adv1"
}
},
{
"term": {
"context.deployment_id": "deploy1"
}
},
{
"term": {
"context.execution_id": "27efcba7-3a60-4270-bbe2-9f17d602dcef"
}
}
]
}
}
}
}
}
return empty results.
the different between them is in the second query, i just add this term:
{
"term": {
"context.execution_id": "27efcba7-3a60-4270-bbe2-9f17d602dcef"
}
}
and in the result we can see that there is result match to that query, but it still not work.
what i'm doing wrong here?
thanks.
By default, ElasticSearch will treat string fields as text and will analyze them (i.e. tokenize, stem etc. before indexing). This means you might not be able to find them when searching for their exact content.
You should make sure the mapping for the execution_id field is not analyzed. Start with GET /_mappings and work from there. :)
