I am query elastic search using sense. When using range filter on field, I get empty hits, but I am able to get results using kibana dashboard. Why is the filter not working? My query:
GET _search
{
"query": {
"bool": {
"must": [
{"match": {"field_name1": "value1"}},
{"match": {"file_name2": "value2"}}
]
}
},
"filter": { <- not working (no data, but gets data from kibana)
"range": {
"#timestamp": {
"gte": "2017-02-18"
}
}
},
"sort": [
{
"#timestamp": {
"order": "desc",
"ignore_unmapped" : true
}
}
]
}
From kibana dashboard when I add the time it add the time:(from:'2017-02-18T10:19:08.680Z',mode:absolute,to:'2017-02-19T10:19:08.680Z')) and I am able to see results. The dashboard also adds some other stuff like metadata and filter with negate but I think they do the same. Only the time part seem to be different. So why the difference and is my query correct? The sample url:
https://elasticsearch/app/kibana#/discover?
_g=(refreshInterval:(display:Off,pause:!f,value:0),time:(from:'2017-02-18T09:23:41.044Z',mode:absolute,to:'2017-02-19T09:23:41.044Z'))
&_a=(columns:!(description,id),filters:!(('$state':(store:appState),meta:(alias:!n,disabled:!f,index:index-value,key:field_name1,negate:!f,value:value1),query:(match:(field_name2:(query:value2,type:phrase))))),index:index-value,interval:auto,query:(query_string:(analyze_wildcard:!t,query:'*')),sort:!('#timestamp',desc),uiState:(),vis:(aggs:!((params:(field:field_name2,orderBy:'2',size:20),schema:segment,type:terms),(id:'2',schema:metric,type:count)),type:histogram))

it's not the same query, in the sense query you asked must query on field1 and field2 but in kibana you didn't

I have two queries that I want to combine, the first one returns a document with some fields.
Now I want to use one of these fields into the new query without creating two separates ones.
Is there a way to combine them in order to accomplish my task?
This is the first query
{
"_source": {
"includes": [
"data.session"
]
},
"query": {
"bool": {
"must": [
{
"match": {
"field1": "9419"
}
},
{
"match": {
"field2": "5387"
}
}
],
"filter": [
{
"range": {
"timestamp": {
"time_zone": "+00:00",
"gte": "2020-10-24 10:16",
"lte": "2020-10-24 11:16"
}
}
}
]
}
},
"size" : 1
}
And this is the response returned:
{
"took": 1,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 109,
"relation": "eq"
},
"max_score": 3.4183793,
"hits": [
{
"_index": "file",
"_type": "_doc",
"_id": "UBYCkgsEzLKoXh",
"_score": 3.4183793,
"_source": {
"data": {
"session": "123456789"
}
}
}
]
}
}
I want to use that "data.session" into another query, instead of rewriting the value of the field by passing the result of the first query.
{
"_source": {
"includes": [
"data.session"
]
},
"query": {
"bool": {
"must": [
{
"match": {
"data.session": "123456789"
}
}
]
}
},
"sort": [
{
"timestamp": {
"order": "asc"
}
}
]
}
If you mean to use the result of the first query as an input to the second query, then it's not possible in Elasticsearch. But if you share your query and use-case, we might suggest you better way.
ElasticSearch does not allow sub queries or inner queries.
I'm getting weird results when querying nested objects. Imagine the following structure:
{ owner.name = "fred",
...,
pets [
{ name = "daisy", ... },
{ name = "flopsy", ... }
]
}
If I only have the document shown above, and I search pets matching this criteria:
pets.name = "daisy" OR
(owner.name = "julie" and pet.name = "flopsy")
I would expect to only get one result ("daisy"), but I'm getting both pet names.
This is one way to reproduce this:
# Create nested mapping
PUT pet-owners
{
"mappings": {
"animals": {
"properties": {
"owner": {"type": "text"},
"pets": {
"type": "nested",
"properties": {
"name": {"type": "text", "fielddata": true}
}
}
}
}
}
}
# Insert nested object
PUT pet-owners/animals/1?op_type=create
{
"owner" : "fred",
"pets" : [
{ "name" : "daisy"},
{ "name" : "flopsy"}
]
}
# Query
GET pet-owners/_search
{ "from": 0, "size": 50,
"query": {
"constant_score": {
"filter": { "bool": {"must": [
{"bool": {"should": [
{"nested": {"query":
{"term": {"pets.name": "daisy"}},
"path":"pets",
"inner_hits": {
"name": "pets_hits_1",
"size": 99,
"_source": false,
"docvalue_fields": ["pets.name"]
}
}},
{"bool": {"must": [
{"term": {"owner": "julie"}},
{"nested": {"query":
{"term": {"pets.name": "flopsy"}},
"path":"pets",
"inner_hits": {
"name": "pets_hits_2",
"size": 99,
"_source": false,
"docvalue_fields": ["pets.name"]
}
}}
]}}
]}}
]}}}},
"_source": false
}
The query returns both pets names (as opposed to the expected one).
Is this behavior normal? Am I doing something wrong, or my reasoning about the nested structure or the query behavior is flawed?
Any help or guidance will be much appreciated.
I'm running this query under ElasticSearch 6.3.x
EDIT: I'm adding the response received, to better illustrate the case
{
"took": 16,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "pet-owners",
"_type": "animals",
"_id": "1",
"_score": 1,
"inner_hits": {
"pets_hits_1": {
"hits": {
"total": 1,
"max_score": 0.6931472,
"hits": [
{
"_index": "pet-owners",
"_type": "animals",
"_id": "1",
"_nested": {
"field": "pets",
"offset": 0
},
"_score": 0.6931472,
"fields": {
"pets.name": [
"daisy"
]
}
}
]
}
},
"pets_hits_2": {
"hits": {
"total": 1,
"max_score": 0.6931472,
"hits": [
{
"_index": "pet-owners",
"_type": "animals",
"_id": "1",
"_nested": {
"field": "pets",
"offset": 1
},
"_score": 0.6931472,
"fields": {
"pets.name": [
"flopsy"
]
}
}
]
}
}
}
}
]
}
}
So we can see that it's not that the query matches and returns the whole existing document, but that it returns each of the pets independently, one inside each of the inner_hits. It's this result that's surprising to me.
(edited) - in summary this issue is around the context of the 'inner_hits':
It looks like the inner_hits 'pets_hits_2' is returning a match because it is belonging to the nested query that simply searches the pets field for 'flopsy'.
As an independent query on our single document, that is a valid hit.
However, because that query is within a list of bool/must queries, where other queries will not match on our document, you may well expect that the inner_hits should pick up on this and therefore not return a hit.
I haven't been able to find any docs to clarify whether this is intentional behaviour or not - might be worth raising with elastic ...
I'm trying to work with Elastic (5.6) and to find a way to retrieve the top documents per some category.
I have an index with the following kind of documents :
{
"#timestamp": "2018-03-22T00:31:00.004+01:00",
"statusInfo": {
"status": "OFFLINE",
"timestamp": 1521675034892
},
"name": "myServiceName",
"id": "xxxx",
"type": "Http",
"key": "key1",
"httpStatusCode": 200
}
}
What i'm trying to do with these, is retrieve the last document (#timestamp-based) per name (my categories), see if its statusInfo.status is OFFLINE or UP and fetch these results into the hits part of a response so I can put it in a Kibana count dashboard or somewhere else (a REST based tool I do not control and can't modify by myself).
Basically, I want to know how many of my services (name) are OFFLINE (statusInfo.status) in their last update (#timestamp) for monitoring purposes.
I'm stuck at the "Get how many of my services" part.
My query so far:
GET actuator/_search
{
"size": 0,
"aggs": {
"name_agg": {
"terms": {
"field": "name.raw",
"size": 1000
},
"aggs": {
"last_document": {
"top_hits": {
"_source": ["#timestamp", "name", "statusInfo.status"],
"size": 1,
"sort": [
{
"#timestamp": {
"order": "desc"
}
}
]
}
}
}
}
},
"post_filter": {
"bool": {
"must_not": {
"term": {
"statusInfo.status.raw": "UP"
}
}
}
}
}
This provides the following response:
{
"all_the_meta":{...},
"hits": {
"total": 1234,
"max_score": 0,
"hits": []
},
"aggregations": {
"name_agg": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "myCategory1",
"doc_count": 225,
"last_document": {
"hits": {
"total": 225,
"max_score": null,
"hits": [
{
"_index": "myIndex",
"_type": "Http",
"_id": "dummy id",
"_score": null,
"_source": {
"#timestamp": "2018-04-06T00:06:00.005+02:00",
"statusInfo": {
"status": "UP"
},
"name": "myCategory1"
},
"sort": [
1522965960005
]
}
]
}
}
},
{other_buckets...}
]
}
}
}
Removing the size make the result contain ALL of the documents, which is not what I need, I only need each bucket content (every one contains one bucket).
Removing the post filter does not appear to do much.
I think this would be feasible in ORACLE SQL with a PARTITION BY OVER clause, followed by a condition.
Does somebody know how this could be achieved ?
If I understand you correctly, you are looking for the latest doc that have status of OFFLINE in each group (grouped by name)?. In that case you can try the query below and the number of items in the bucket should give you the "how many are down" (for up you would change the term in the filter)
NOTE: this is done in latest version, so it uses keyword field instead of raw
POST /index/_search
{
"size": 0,
"query":{
"bool":{
"filter":{
"term": {"statusInfo.status.keyword": "OFFLINE"}
}
}
},
"aggs":{
"services_agg":{
"terms":{
"field": "name.keyword"
},
"aggs":{
"latest_doc":{
"top_hits": {
"sort": [
{
"#timestamp":{
"order": "desc"
}
}
],
"size": 1,
"_source": ["#timestamp", "name", "statusInfo.status"]
}
}
}
}
}
}
I wanna perform a full-text search, but I also wanna use one or many possible filters. The simplified structure of my document, when searching with /things/_search?q=*foo*:
{
"took": 5,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "things",
"_type": "thing",
"_id": "63",
"_score": 1,
"fields": {
"name": [
"foo bar"
],
"description": [
"this is my description"
],
"type": [
"inanimate"
]
}
}
]
}
}
This works well enough, but how do I combine filters with a query? Let's say I wanna search for "foo" in an index with multiple documents, but I only want to get those with type == "inanimate"?
This is my attempt so far:
{
"query": {
"filtered": {
"query": {
"query_string": {
"query": "*foo*"
}
},
"filter": {
"bool": {
"must": {
"term": { "type": "inanimate" }
}
}
}
}
}
}
When I remove the filter part, it returns an accurate set of document hits. But with this filter-definition it does not return anything, even though I can manually verify that there are documents with type == "inanimate".
Since you have not done explicit mapping, term query is looking for an exact match. you need to add "index : not_analyzed" to type field and then your query will work.
This will give you correct documents
{
"query": {
"match": {
"type": "inanimate"
}
}
}
but this is not the solution, You need do explicit mapping as I said.
I have query with multi_match in Elasticsearch:
{
"query": {
"multi_match": {
"query": "luk",
"fields": [
"xml_string.autocomplete",
"state"
]
}
},
"size": 10,
"fields": [
"xml_string",
"state"
]
}
It works great, result returns expected value:
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 0.41179964,
"hits": [
{
"_index": "documents",
"_type": "document",
"_id": "11",
"_score": 0.41179964,
"fields": {
"xml_string": "Lukas bla bla bla",
"state": "new"
}
}
]
}
}
I've searched a lot, but I am not able to find out which field matched the query(if it was xml_string OR state)
I have found solution: I have used highlight feature and it's working great
This is how my curl looks like:
curl -X GET 'http://xxxxx.com:9200/documents/document/_search?load=false&size=10&pretty' -d '{
"query": {
"multi_match": {
"query": "123",
"fields": ["some_field", "another_field"]
}
},
"highlight": {
"fields": {
"some_field": {},
"another_field": {}
}
},
"size": 10,
"fields": ["field","another_field"]
}'
As far as I know there is no feature for telling you which field has matched the query.
But you can use the explain feature for debugging your query. You only have to add to your query the pamameter &explain=true. With this parameter you will see an explanation for each field of why it is in the result set and you will guess which field matched the query.
