ElasticSearch Range query - elasticsearch

I have created the index by using the following mapping:
put test1
{
"mappings": {
"type1": {
"properties": {
"age": {
"type": "text",
"fields": {
"raw": {
"type": "keyword",
"ignore_above": 32766
}
}
}
}
}
}
}
Added following documents into index:
PUT test1/type1/1/_create
{
"age":50
}
PUT test1/type1/2/_create
{
"age":100
}
PUT test1/type1/3/_create
{
"age":150
}
PUT test1/type1/4/_create
{
"age":200
}
I have used the following range query to fetch result:
GET test1/_search
{
"query": {
"range" : {
"age" : {
"lte" : 150
}
}
}
}
It is giving me the following response :
{
"took": 3,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"skipped": 0,
"failed": 0
},
"hits": {
"total": 2,
"max_score": 1,
"hits": [
{
"_index": "test1",
"_type": "type1",
"_id": "2",
"_score": 1,
"_source": {
"age": 100
}
},
{
"_index": "test1",
"_type": "type1",
"_id": "3",
"_score": 1,
"_source": {
"age": 150
}
}
]
}
}
the above response not showing document having age is 50 it is showing only age is 100 and 150. As 50 also less than 200. What is wrong here?
Can anyone help me to get a valid result?
In my schema age field type text, I don't want to change it.
How can I get a valid result?

Because age field type is text, the range query is using alphabetically order. So the results are correct:
"100"<"150"
"150"="150"
"50">"150"
If you are ingesting only numbers in age field, you should change the age field type to number, or add another inner field as number, just you did with raw inner field.

UPDATE: Tested on local system and it is working.
NOTE: Ideally, you would want the mappings to be correct, but if there is no other choice and you are not the person to decide on the mapping then you can still achieve it by following.
For ES version 6.3 onwards, try this.
GET test1/type1/_search
{
"query": {
"bool" : {
"must" : {
"script" : {
"script" : {
"source": "Integer.parseInt(doc['age.raw'].value) <= 150",
"lang": "painless"
}
}
}
}
}
}

Type for your field age in mapping is set to text. That is reason it is doing dictionary sorting where 50 > 150. Please use long data type. https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping.html

Query on Elastic Search on multiple criterias

I have this document in elastic search
{
"_index" : "master",
"_type" : "_doc",
"_id" : "q9IGdXABeXa7ITflapkV",
"_score" : 0.0,
"_source" : {
"customer_acct" : "64876457056",
"ssn_number" : "123456789",
"name" : "Julie",
"city" : "NY"
}
I wanted to query the master index , with the customer_acct and ssn_number to retrive the entire document. I wanted to disable scoring and relevance , I have used the below query
curl -X GET "localhost/master/_search/?pretty" -H 'Content-Type: application/json' -d'
{
"query": {
"term": {
"customer_acct": {
"value":"64876457056"
}
}
}
}'
I need to include the second criteria in the term query as well which is the ssn_number, how would I do that? , I want to turn off scoring and relevance would that be possible, I am new to Elastic Search and how would I fit the second criteria on ssn_number in the above query that I have tried?
First, you need to define the proper mapping of your index. your customer_acct and ssn_number are of numeric type but you are storing it as a string. Also looking at your sample I can see you have to use long to store them. and then you can just use filter context in your query as you don't need score and relevance in your result. Read more about filter context in official ES doc as well as below snippet from the link.
In a filter context, a query clause answers the question “Does this
document match this query clause?” The answer is a simple Yes or
No — no scores are calculated. Filter context is mostly used for
filtering structured data,
which is exactly your use-case.
1. Index Mapping
{
"mappings": {
"properties": {
"customer_acct": {
"type": "long"
},
"ssn_number" :{
"type": "long"
},
"name" : {
"type": "text"
},
"city" :{
"type": "text"
}
}
}
}
2. Index sample docs
{
"name": "Smithe John",
"city": "SF",
"customer_acct": 64876457065,
"ssn_number": 123456790
}
{
"name": "Julie",
"city": "NY",
"customer_acct": 64876457056,
"ssn_number": 123456789
}
3. Main search query to filter without the score
{
"query": {
"bool": {
"filter": [ --> only filter clause
{
"term": {
"customer_acct": 64876457056
}
},
{
"term": {
"ssn_number": 123456789
}
}
]
}
}
}
Above search query gives below result:
{
"took": 186,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"skipped": 0,
"failed": 0
},
"hits": {
"total": {
"value": 1,
"relation": "eq"
},
"max_score": 0.0,
"hits": [
{
"_index": "so-master",
"_type": "_doc",
"_id": "1",
"_score": 0.0, --> notice score is 0.
"_source": {
"name": "Smithe John",
"city": "SF",
"customer_acct": 64876457056,
"ssn_number": 123456789
}
}
]
}
}

how to make proper query to select by ID and later update using elastic search?

I am very new in ES and I am trying to figure out some things.
I did a basic query this way
GET _search
{
"query": {
"match_all": {}
}
}
and I got this...
{
"took": 7,
"timed_out": false,
"_shards": {
"total": 768,
"successful": 768,
"failed": 0
},
"hits": {
"total": 456,
"max_score": 1,
"hits": [
{
"_index": "sometype_1",
"_type": "sometype",
"_id": "12312321312312",
"_score": 1,
"_source": {
"readModel": {
"id": "asdfqwerzcxv",
"status": "active",
"hidden": false
},
"model": {
"id": "asdfqwerzcxv",
"content": {
"objectId": "421421312312",
"message": "hello world",
..... //the rest of the object...
So right now I want to get the object with id asdfqwerzcxv and I did this:
GET _search
{
"query": {
"match" : {
"id" :"asdfqwerzcxv"
}
}
}
But of course is not working... I also tried to make the whole route like:
GET _search
{
"query": {
"match" : {
"_source" :{
"readModel" : {
"id": "asdfqwerzcxv"
}
}
}
}
}
But no luck...
is there a way to do this? could someone help me?
Thanks
You need to use the full-qualified field name, try this:
GET _search
{
"query": {
"match" : {
"readModel.id" :"asdfqwerzcxv"
^
|
add this
}
}
}

Elasticsearch aggregation turns results to lowercase

I've been playing with ElasticSearch a little and found an issue when doing aggregations.
I have two endpoints, /A and /B. In the first one I have parents for the second one. So, one or many objects in B must belong to one object in A. Therefore, objects in B have an attribute "parentId" with parent index generated by ElasticSearch.
I want to filter parents in A by children attributes of B. In order to do it, I first filter children in B by attributes and get its unique parent ids that I'll later use to get parents.
I send this request:
POST http://localhost:9200/test/B/_search
{
"query": {
"query_string": {
"default_field": "name",
"query": "derp2*"
}
},
"aggregations": {
"ids": {
"terms": {
"field": "parentId"
}
}
}
}
And get this response:
{
"took": 91,
"timed_out": false,
"_shards": {
"total": 5,
"successful": 5,
"failed": 0
},
"hits": {
"total": 3,
"max_score": 1,
"hits": [
{
"_index": "test",
"_type": "child",
"_id": "AU_fjH5u40Hx1Kh6rfQG",
"_score": 1,
"_source": {
"parentId": "AU_ffvwM40Hx1Kh6rfQA",
"name": "derp2child2"
}
},
{
"_index": "test",
"_type": "child",
"_id": "AU_fjD_U40Hx1Kh6rfQF",
"_score": 1,
"_source": {
"parentId": "AU_ffvwM40Hx1Kh6rfQA",
"name": "derp2child1"
}
},
{
"_index": "test",
"_type": "child",
"_id": "AU_fjKqf40Hx1Kh6rfQH",
"_score": 1,
"_source": {
"parentId": "AU_ffvwM40Hx1Kh6rfQA",
"name": "derp2child3"
}
}
]
},
"aggregations": {
"ids": {
"doc_count_error_upper_bound": 0,
"sum_other_doc_count": 0,
"buckets": [
{
"key": "au_ffvwm40hx1kh6rfqa",
"doc_count": 3
}
]
}
}
}
For some reason, the filtered key is returned in lowercase, hence not being able to request parent to ElasticSearch
GET http://localhost:9200/test/A/au_ffvwm40hx1kh6rfqa
Response:
{
"_index": "test",
"_type": "A",
"_id": "au_ffvwm40hx1kh6rfqa",
"found": false
}
Any ideas on why is this happening?
The difference between the hits and the results of the aggregations is that the aggregations work on the created terms. They will also return the terms. The hits return the original source.
How are these terms created? Based on the chosen analyser, which in your case is the default one, the standard analyser. One of the things this analyser does is lowercasing all the characters of the terms. Like mentioned by Andrei, you should configure the field parentId to be not_analyzed.
PUT test
{
"mappings": {
"B": {
"properties": {
"parentId": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
I am late from the party but I had the same issue and understood that it caused by the normalization.
You have to change the mapping of the index if you want to prevent any normalization changes the aggregated values to lowercase.
You can check the current mapping in the DevTools console by typing
GET /A/_mapping
GET /B/_mapping
When you see the structure of the index you have to see the setting of the parentId field.
If you don't want to change the behaviour of the field but you also want to avoid the normalization during the aggregation then you can add a sub-field to the parentId field.
For changing the mapping you have to delete the index and recreate it with the new mapping:
creating the index
Adding multi-fields to an existing field
In your case it looks like this (it contains only the parentId field)
PUT /B/_mapping
{
"properties": {
"parentId": {
"type": "text",
"fields": {
"keyword": {
"type": "keyword"
}
}
}
}
}
then you have to use the subfield in the query:
POST http://localhost:9200/test/B/_search
{
"query": {
"query_string": {
"default_field": "name",
"query": "derp2*"
}
},
"aggregations": {
"ids": {
"terms": {
"field": "parentId.keyword",
"order": {"_key": "desc"}
}
}
}
}

ElasticSearch - Match (email value) returns wrong registers

I'm using match to search for a specific email but the result is wrong. The match property brings me results similar. If the result exists, the result displays on first lines but when the results not exists, it brings me result by same domain.
Here is my query:
{
"query": {
"match" : {
"email" : "placplac#xxx.net"
}
}
}
This email doesn't exist in my base but returning values like banana#xxx.net, ronyvon#xxx.net*, etc.
How can i force to return only if the value is equal from the query?
Thank in advance.
You need to put "index":"not_analyzed" on the "email" field. That way, the only terms that are queried against are the exact values that have been stored to that field (as opposed to the case with the standard analyzer, which is the default used if no analyzer is listed).
To illustrate, I set up a simple mapping with the email field not analyzed, and added two simple docs:
DELETE /test_index
PUT /test_index
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
},
"mappings": {
"doc": {
"properties": {
"email": {
"type": "string",
"index": "not_analyzed"
}
}
}
}
}
PUT /test_index/doc/1
{"email": "placplac#xxx.net"}
PUT /test_index/doc/2
{"email": "placplac#nowhere.net"}
Now your match query will return only the document that matches the query exactly:
POST /test_index/_search
{
"query": {
"match" : {
"email" : "placplac#xxx.net"
}
}
}
...
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1,
"hits": [
{
"_index": "test_index",
"_type": "doc",
"_id": "1",
"_score": 1,
"_source": {
"email": "placplac#xxx.net"
}
}
]
}
}
Here is the code I used:
http://sense.qbox.io/gist/12763f63f2a75bf30ff956c25097b5955074508a
PS: What you actually probably want here is a term query or even term filter, since you don't want any analysis on the query text. So maybe something like:
POST /test_index/_search
{
"query": {
"constant_score": {
"filter": {
"term": {
"email": "placplac#xxx.net"
}
}
}
}
}

How to use _timestamp in a scripted update

I was trying to come up with an elegant answer to this question and ran into an unexpected problem. The basic idea is to update a document based on its current timestamp. Seems straightforward enough, but I seem to be missing something. At the bottom of the Update API page, the ES docs say:
It also allows to update the ttl of a document using ctx._ttl and timestamp using ctx._timestamp. Note that if the timestamp is not updated and not extracted from the _source it will be set to the update date.
The ES documentation is often enigmatic at best, especially when it comes to scripting, but I took this to mean that I could use the _timestamp field in an update script.
So I set up a simple index with a timestamp:
PUT /test_index
{
"settings": {
"number_of_shards": 1,
"number_of_replicas": 0
},
"mappings": {
"doc": {
"_timestamp": {
"enabled": true,
"store": true,
"path": "doc_date",
"format" : "YYYY-MM-dd"
},
"properties": {
"doc_date": {
"type": "date",
"format" : "YYYY-MM-dd"
},
"doc_text": {
"type": "string"
}
}
}
}
}
and added some docs:
POST /test_index/_bulk
{"index":{"_index":"test_index","_type":"doc","_id":1}}
{"doc_text":"doc1", "doc_date":"2015-2-5"}
{"index":{"_index":"test_index","_type":"doc","_id":2}}
{"doc_text":"doc2", "doc_date":"2015-2-10"}
{"index":{"_index":"test_index","_type":"doc","_id":3}}
{"doc_text":"doc3", "doc_date":"2015-2-15"}
If I query for the first doc, I get back what I expect:
POST /test_index/_search
{
"query": {
"match": {
"doc_text": "doc1"
}
},
"fields": [
"_timestamp",
"_source"
]
}
...
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1.4054651,
"hits": [
{
"_index": "test_index",
"_type": "doc",
"_id": "1",
"_score": 1.4054651,
"_source": {
"doc_text": "doc1",
"doc_date": "2015-2-5"
},
"fields": {
"_timestamp": 1423094400000
}
}
]
}
}
So far so good. Now I want to conditionally update the first doc, based on its timestamp. First I tried this, and got an error:
POST /test_index/doc/1/_update
{
"script": "if(ctx._timestamp < new_ts){ctx._source.doc_date=new_date;ctx._source.doc_text=new_text}",
"params": {
"new_ts": 1423526400000,
"new_date": "2015-2-10",
"new_text": "doc1-updated"
}
}
...
{
"error": "ElasticsearchIllegalArgumentException[failed to execute script]; nested: PropertyAccessException[[Error: could not access: _timestamp; in class: java.util.HashMap]\n[Near : {... if(ctx._timestamp < new_ts){ctx._ ....}]\n ^\n[Line: 1, Column: 4]]; ",
"status": 400
}
Then I tried this:
POST /test_index/doc/1/_update
{
"script": "if(ctx[\"_timestamp\"] < new_ts){ctx._source.doc_date=new_date;ctx._source.doc_text=new_text}",
"params": {
"new_ts": 1423526400000,
"new_date": "2015-2-10",
"new_text": "doc1-updated"
}
}
...
{
"_index": "test_index",
"_type": "doc",
"_id": "1",
"_version": 2
}
I didn't get an error, but the update didn't happen:
POST /test_index/_search
{
"query": {
"match": {
"doc_text": "doc1"
}
},
"fields": [
"_timestamp",
"_source"
]
}
...
{
"took": 2,
"timed_out": false,
"_shards": {
"total": 1,
"successful": 1,
"failed": 0
},
"hits": {
"total": 1,
"max_score": 1.287682,
"hits": [
{
"_index": "test_index",
"_type": "doc",
"_id": "1",
"_score": 1.287682,
"_source": {
"doc_text": "doc1",
"doc_date": "2015-2-5"
},
"fields": {
"_timestamp": 1423094400000
}
}
]
}
}
Just out of curiosity, I inverted the conditional:
POST /test_index/doc/1/_update
{
"script": "if(ctx[\"_timestamp\"] > new_ts){ctx._source.doc_date=new_date;ctx._source.doc_text=new_text}",
"params": {
"new_ts": 1423526400000,
"new_date": "2015-2-10",
"new_text": "doc1-updated"
}
}
with the same result: no update.
Okay, so as a sanity check I tried to set the timestamp, and got an error:
POST /test_index/doc/1/_update
{
"script": "ctx._source.doc_date=new_date;ctx._source.doc_text=new_text;ctx._timestamp=new_ts",
"params": {
"new_ts": 1423526400000,
"new_date": "2015-2-10",
"new_text": "doc1-updated"
}
}
...
{
"error": "ClassCastException[java.lang.Long cannot be cast to java.lang.String]",
"status": 500
}
I also tried it with "ctx[\"_timestamp\"]=new_ts;", and got the same error.
So it seems that the _timestamp field is not available to the script, even though the documentation says it is. What am I doing wrong?
I also tried updating without the conditional or updating the timestamp, and it worked as expected.
I used Elasticsearch version 1.3.4 (with dynamic scripting enabled, obviously), running on an Ubuntu 12 VM.
Here is the code I used to set this up:
http://sense.qbox.io/gist/ca2b3c6b84572e5f87d57d22f8c38252fa4ee216
