I am using a functionScoreQuery provided by the elastic-builder npm to query my elasticsearch, query is getting created but i am not able to get outer query params for my query as shown below.
i.e the outer query params are missing and that is why the query does not execute so i had to manually append query { } in my body. So if anyone can help me out and tell me what i am missing in my npm query to get those query params.
var not_body = elasticbuilder.functionScoreQuery()
.query(elasticbuilder.matchAllQuery())
.functions([
elasticbuilder.weightScoreFunction()
.filter(elasticbuilder.boolQuery().mustNot([
elasticbuilder.hasChildQuery(
elasticbuilder.boolQuery().must([
elasticbuilder.matchPhraseQuery("name", "raju" )
])
).type('student')
]))
.weight(2),
elasticbuilder.weightScoreFunction()
.filter(elasticbuilder.boolQuery().must([
elasticbuilder.hasChildQuery(
elasticbuilder.boolQuery().must([
elasticbuilder.matchPhraseQuery("class", "12")
])
).type('info')
]))
.weight(2)
]).minScore(4).scoreMode('sum');
Current Output body via this query:
{
"function_score": {
"functions": [
{
"filter": {
"bool": {
"must_not": {
"has_child": {
"query": {
"bool": {
"must": {
"match_phrase": {
"name" : "raju"
}
}
}

"type": "student"

},
"weight": 2

}
}
},
"weight": 2
}
],
"query": {
"match_all": {}
},
"min_score": 4,
"score_mode": "sum"
}
}
Expected Output body:

"functions": [
{
"filter": {
"bool": {
"must_not": {
"has_child": {
"query": {

You should wrap this in a elasticbuilder.requestBodySearch()
In your case
elasticbuilder.requestBodySearch().query(not_body)
should do the job

I'd like to use not equal in my filter but it doesn't work [13:24] [bool] failed to parse field [filter]:
"query": {
"bool": {
"filter": [
{
"must_not" : {
"term" : {
"status" : "DECLINED"
}
}
},
{
"term": { "type": "ORDER"}
}
]
}
}
it works if I put the must_not under query like below. How can I put not equal in filter?
"query": {
"bool": {
"must_not": {
"term": {
"status": "DECLINED"
}
},
"filter": ...
May be one more bool needed inside the filter ?
/_search
{
"query": {
"bool": {
"filter": {
"bool": {
"must": [
{
"term": { "type": "ORDER"}
}
],
"must_not": [
{
"term": {
"status": "DECLINED"
}
}
]
}
}
}
}
}
With the following mapping:
"categories": {
"type": "nested",
"properties": {
"category": {
"type": "integer"
},
"score": {
"type": "float"
}
}
},
I want to use the categories field to return documents that either:
have a score above a threshold in a given category, or
do not have the categories field
This is my query:
{
"query": {
"bool": {
"should": [
{
"nested": {
"path": "categories",
"query": {
"bool": {
"must": [
{
"terms": {
"categories.category": [
<id>
]
}
},
{
"range": {
"categories.score": {
"gte": 0.5
}
}
}
]
}
}
}
},
{
"bool": {
"must_not": [
{
"exists": {
"field": "categories"
}
}
]
}
}
],
"minimum_should_match": 1
}
}
}
It correctly returns documents both with and without the categories field, and orders the results so the ones I want are first, but it doesn't filter the results having score below the 0.5 threshold.
Great question.
That is because categories is not exactly a field from the elasticsearch point of view[a field on which inverted index is created and used for querying/searching] but categories.category and categories.score is.
As a result categories being not found in any document, which is actually true for all the documents, you observe the result what you see.
Modify the query to the below and you'd see your use-case working correctly.
POST <your_index_name>/_search
{
"query": {
"bool": {
"should": [
{
"nested": {
"path": "categories",
"query": {
"bool": {
"must": [
{
"terms": {
"categories.category": [
"100"
]
}
},
{
"range": {
"categories.score": {
"gte": 0.5
}
}
}
]
}
}
}
},
{
"bool": {
"must_not": [ <----- Note this
{
"nested": {
"path": "categories",
"query": {
"bool": {
"must": [
{
"exists": {
"field": "categories.category"
}
},
{
"exists": {
"field": "categories.score"
}
}
]
}
}
}
}
]
}
}
],
"minimum_should_match": 1
}
}
}
I have a query as follows to use function_score but it gives an error that the query is malformed and [END_OBJECT] is expected but found [FIELD_NAME]. I have checked the documentation and couldn't find what is incorrect or inconsistent with this. I haven't added any script in script_score here but even when I tried with adding script it gave the same problem.
{
"from": 0,
"query": {
"function_score": {
"query": {
"bool": {
"filter": [
{
"bool": {
"should": [
{
"bool": {
"must": [
{
"match": {
"address.area.area.raw": "Durbarmarg"
}
},
{
"match": {
"address.area.city.raw": "Kathmandu"
}
},
{
"match": {
"address.area.district.raw": "Kathmandu"
}
},
{
"match": {
"address.area.state.raw": "State-3"
}
},
{
"match": {
"address.area.country.raw": "Nepal"
}
}
]
}
},
{
"nested": {
"inner_hits": {},
"path": "branchAddress",
"query": {

}
}
}
}

}
}
],
"must": [

}
}
],
"must_not": [],
"should": []
}
}
},
"script_score": {}
},
"size": 10
}
The error is as bellow:
raise HTTP_EXCEPTIONS.get(status_code, TransportError)(status_code, error_message, additional_info)
elasticsearch.exceptions.RequestError: TransportError(400, 'parsing_exception', '[function_score] malformed query, expected [END_OBJECT] but found [FIELD_NAME]')
The script_score section is not at the right place, it needs to be a sibling of the inner query:
{
"from": 0,
"query": {
"function_score": {
"query": {
...
},
"script_score": {} <--- script_score goes here
}
},
"size": 10
}
`"query": {
"function_score": {
"query": {
"bool": {
"must": [],
"should": [],
"filter": [
{
"terms": {
"category": "type-1",
"product": "product-A"
},
"terms": {
"category": "type-2",
"product": "product-B"
}
}
]
}
},
"functions": []
}
},`
I want to pass multiple combination query like above is it possible, what should be the correct query format
in sql my query would be
select * from product where (category='type1' and product=product-A) or (category='type2' and product=product-B) or (category='type3' and product=product-C)
i want to replicate above query
If you want to make a OR statement in a bool query you should is a nested bool query with multiple should clause.
so try :
{
"query": {
"function_score": {
"query": {
"bool": {
"must": [],
"should": [],
"filter": [
{
"bool": {
"should": [
{
"bool": {
"must": [
{
"term": {
"category": "type-1"
}
},
{
"term": {
"product": "product-A"
}
}
]
}
},
{
"bool": {
"must": [
{
"term": {
"category": "type-2"
}
},
{
"term": {
"product": "product-B"
}
}
]
}
}
]
}
}
]
}
}
}
},
"functions": []
}
and if you have no must clause you can move your filters clauses into the main should as only document that matchs at least one of the clause will match.
I'm running Elasticsearch 1.5.2 and trying the following query:
{
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"term": {
"gender": "male"
}
}
]
}
},
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"should": [
{
"term": {
"top_users": 1,
"boost": 2
}
}
]
}
}
}
}
}
Everything is fine until I add the "boost": 2 to the should -> term part. The complete query is much more complex, that's why I need to boost, but the remaining queries don't make any difference: ES returns an error 400 if a term query gets a boost argument:
QueryParsingException[[index_name] [_na] query malformed, must start with start_object]
Any suggestions?
It should be like this:
{
"query": {
"filtered": {
"filter": {
"bool": {
"must": [
{
"term": {
"gender": "male"
}
}
]
}
},
"query": {
"bool": {
"must": [
{
"match_all": {}
}
],
"should": [
{
"term": {
"top_users": {
"value": "1",
"boost": 2
}
}
}
]
}
}
}
}
}
