Here is my data in Elasticsearch - I kept Tags as nested object
PUT myblog/3
{
"id" : 10003,
"tags" : [
{
"tag" : 45647
},
{
"tag" : 45648
}
]
}
PUT myblog/4
{
"id" : 10004,
"tags" : [
{
"tag" : 45647
}
]
}
PUT myblog/5
{
"id" : 10005,
"tags" : [
{
"tag" : 45648
}
]
}
I want to retrieve documents with tag is 45647 & 45648. I tried it in this way
GET myblog/_search
{
"query": {
"nested": {
"path": "tags",
"query": {
"bool": {
"must": [
{ "match": { "tags.tag": 45648}},
{ "match": { "tags.tag": 45647}}
]
}
}
}
}
}
But it is not returning the expected result. What is missing in my query to get expected result?
You're almost there. You need two nested clauses since each nested element is a different document underneath. Try like this:
GET myblog/_search
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "tags",
"query": {
"match": {
"tags.tag": 45648
}
}
}
},
{
"nested": {
"path": "tags",
"query": {
"match": {
"tags.tag": 45647
}
}
}
}
]
}
}
}

I have the below JSON object as _source in Elastic search. I need to filter the source object based on conditions. For example, I need only JSON with applied_as == "COMMISSION"
"_source": {
"factor" : [
{
"some_amount_usd" : [
{
"applied_as" : "TCKT_CNT",
"version" : "8",
"factor_value" : "1.12",
"start_date" : "2022-01-01"
},
{
"applied_as" : "TCKT_CNT",
"version" : "8",
"factor_value" : "1.12",
"start_date" : "2022-02-01"
},
{
"applied_as" : "COMMISSION",
"version" : "8",
"factor_value" : "1.12",
"start_date" : "2022-02-01"
},
]
}
]
}
I am using this documentation.
https://www.elastic.co/guide/en/elasticsearch/reference/7.17/search-fields.html#source-filtering
I am currently using this query with no luck. What am I missing?
GET form_some_index/_search
{
"query": {
"match": {
"factor.some_amount_usd.applied_as": "COMMISSION"
}
}
}
You can start using Nested Query.
{
"query": {
"bool": {
"must_not": [
{
"nested": {
"path": "factor",
"query": {
"nested": {
"path": "factor.some_amount_usd",
"query": {
"bool": {
"must_not": [
{
"term": {
"factor.some_amount_usd.applied_as.keyword": {
"value": "COMMISSION"
}
}
}
]
}
}
}
}
}
}
]
}
}
}
I have the following query:
GET /networkcollection/branch_routers/_search/
{
"query": {
"nested": {
"path": "queries",
"query": {
"bool": {
"must": [
{ "match":
{ "queries.dateQuery": "20160101T200000.000Z" }
}
]
}
},
"inner_hits" : {}
}
}
}
This returns both the "hits" object (the entire document), as well as the "inner_hits" object (nested inside of hits).
Is there a way to for me to only return the matched "queries" element(s) which appear in the "inner_hits" results, without getting the whole document?
Should be able to achieve it by disabling source-field at top-level by specifying "_source" : false
POST /networkcollection/branch_routers/_search/
{
"_source" : false,
"query": {
"nested": {
"path": "queries",
"query": {
"bool": {
"must": [
{ "match":
{ "queries.dateQuery": "20160101T200000.000Z" }
}
]
}
},
"inner_hits" : {}
}
}
}
I am trying to query for the following document in my elasticsearch:
"amenity": [
"Free Wifi",
"Free Breakfast",
"Veg Only",
"Swimming Pool",
"Newspaper",
"Bar",
"Credit Card",
"Pickup & Drop",
"Gym",
"Elevator",
"Valet Parking"
],
"dodont": [
{
"do_or_dont": "Do",
"what": "Vegetarians"
},
{
"do_or_dont": "Do",
"what": "Family"
},
{
"do_or_dont": "Dont",
"what": "Loud Music"
},
{
"do_or_dont": "Dont",
"what": "Booze"
}
]
and here is the query I have written:
"filter": {
"and": {
"filters": [
{
"nested" : {
"path" : "dodont",
"filter" : {
"bool" : {
"must": [{"and" : [
{
"term" : {"dodont.do_or_dont" : "Do"}
},
{
"term" : {"dodont.what" : "Vegetarians"}
}
]},
{"and" : [
{
"term" : {"dodont.do_or_dont" : "Do"}
},
{
"term" : {"dodont.what" : "Family"}
}
]}]
}
}
}
}
]
}
}
Now this query returns empty result, but when I change the "must" to "should" in the bool in above code, it returns the above document as the result (there is only 1 document matching this filter the one shown above), but ideally, the "must" condition should return the above document, I want to pass multiple objects for Do's and donts and I only want the results which match all of them, but I am not able to do so. How should I go about it?
You need to split out the two conditions on your nested document, since each element of the dodont nested array is conceptually a separate document:
{
"filter": {
"and": {
"filters": [
{
"nested": {
"path": "dodont",
"filter": {
"and": [
{
"term": {
"dodont.do_or_dont": "Do"
}
},
{
"term": {
"dodont.what": "Vegetarians"
}
}
]
}
}
},
{
"nested": {
"path": "dodont",
"filter": {
"and": [
{
"term": {
"dodont.do_or_dont": "Do"
}
},
{
"term": {
"dodont.what": "Family"
}
}
]
}
}
}
]
}
}
}
Hi I am trying to get a query to filter based on values in an array of objects, the structure is like this
{
"_index": "test",
"_type": "home",
"_id": "1247816",
"_score": 1,
"_source": {
"TranCust": {
"CustId": 1247816,
"sourceNodeName": "SRC"
},
"TranList": [
{
"TranId": 2431015,
"batchNr": "211"
},
{
"TranId": 2431016,
"batchNr": "213"
}
]
}
}
as an example, i would like to find all documents with a TranId of 2431015, my query looks like this
{
"query": {
"bool": {
"must": [
{
"nested": {
"path": "TranList",
"query": {
"bool": {
"must": [
{
"match": {
"TranId": "2431015"
}
}
]
}
}
}
}
]
}
}
}
it seems to return no results, is there a better way to try and write this query ?
EDIT,
here are the mappings put in
{
"mappings": {
"home": {
"properties": {
"TranCust": {
"type": "object"
}
},
"TranList": {
"type": "nested"
}
}
}
}
}
ok, so after lots of attempts this is how i got it to work
{
"query": {
"bool": {
"must": [{
"nested": {
"path": "TranList",
"query": {
"bool": {
"must": [{
"match": {
"TranList.TranId": "2431015"
}
}]
}
}
}
}]
}
}
}
Not sure what was your ES version, but the following should ideally work for ES 6.x+ versions. You don't actually need to wrap your nested query with bool:must
{
"query": {
"nested" : {
"path" : "TranList",
"query" : {
"bool" : {
"must" : [
{ "match" : {"TranList.TranId" : "2431015"} }
]
}
}
}
}
}
{
"query": {
"query_string": {
"default_field": "TranList.TranId",
"query": "2431015"
}
}
}
I have a list, array or whichever language you are familiar. E.g. names : ["John","Bas","Peter"] and I want to query the name field if it matches one of those names.
One way is with OR Filter. e.g.
{
"filtered" : {
"query" : {
"match_all": {}
},
"filter" : {
"or" : [
{
"term" : { "name" : "John" }
},
{
"term" : { "name" : "Bas" }
},
{
"term" : { "name" : "Peter" }
}
]
}
}
}
Any fancier way? Better if it's a query than a filter.
{
"query": {
"filtered" : {
"filter" : {
"terms": {
"name": ["John","Bas","Peter"]
}
}
}
}
}
Which Elasticsearch rewrites as if you hat used this one
{
"query": {
"filtered" : {
"filter" : {
"bool": {
"should": [
{
"term": {
"name": "John"
}
},
{
"term": {
"name": "Bas"
}
},
{
"term": {
"name": "Peter"
}
}
]
}
}
}
}
}
When using a boolean filter, most of the time, it is better to use the bool filter than and or or. The reason is explained on the Elasticsearch blog: http://www.elasticsearch.org/blog/all-about-elasticsearch-filter-bitsets/
As I tried the filtered query I got no [query] registered for [filtered], based on answer here it seems the filtered query has been deprecated and removed in ES 5.0. So I provide using:
{
"query": {
"bool": {
"filter": {
"terms": {
"name": ["John","Bas","Peter"]
}
}
}
}
}
example query = filter by keyword and a list of values
{
"query": {
"bool": {
"must": [
{
"term": {
"fguid": "9bbfe844-44ad-4626-a6a5-ea4bad3a7bfb.pdf"
}
}
],
"filter": {
"terms": {
"page": [
"1",
"2",
"3"
]
}
}
}
}
}
