I'm using the official Docker image for Elasticsearch OSS (docker.elastic.co/elasticsearch/elasticsearch-oss:6.2.4) and can't seem to get script_score working at all. It seems like scripting isn't enabled.
For example, this:
POST http://localhost:9200/address/address/_search
{
"query": {
"function_score": {
"query": {
"match": {
"fullAddress": {
"query": "13 fake",
"operator": "and"
}
}
},
"script_score": {
"lang": "expression",
"source": "doc['flatNumber'].length"
}
}
}
}
gives me this:
{
"error": {
"root_cause": [
{
"type": "parsing_exception",
"reason": "script_score query does not support [source]",
"line": 13,
"col": 15
}
],
"type": "parsing_exception",
"reason": "script_score query does not support [source]",
"line": 13,
"col": 15
},
"status": 400
}
I tried enabling it:
PUT http://localhost:9200/_cluster/settings
{
"persistent": {
"script.engine.groovy.inline.aggs": "on"
}
}
but to no avail:
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "persistent setting [script.engine.groovy.inline.aggs], not recognized"
}
],
"type": "illegal_argument_exception",
"reason": "persistent setting [script.engine.groovy.inline.aggs], not recognized"
},
"status": 400
}
How do I get script_score working?
You're simply missing a script section in your script_score. Modify it like this and it will work:
"script_score": {
"script": {
"lang": "expression",
"source": "doc['flatNumber'].length"
}
}

I'm trying to use ElasticSearch v. 7.11.1 on Windows 10. I don't know how to make multi_terms aggregation work. This query:
{
"aggs": {
"test_agg": {
"multi_terms": {
"terms": [{
"field": "JobTitle.keyword"
}, {
"field": "AboutMe.keyword"
}]
}
}
}
}
gives me this:
{
"error": {
"root_cause": [
{
"type": "parsing_exception",
"reason": "Unknown aggregation type [multi_terms] did you mean [rare_terms]?",
"line": 4,
"col": 22
}
],
"type": "parsing_exception",
"reason": "Unknown aggregation type [multi_terms] did you mean [rare_terms]?",
"line": 4,
"col": 22,
"caused_by": {
"type": "named_object_not_found_exception",
"reason": "[4:22] unknown field [multi_terms]"
}
},
"status": 400
}
but this query:
{
"aggs": {
"test_agg": {
"terms":
{
"field": "JobTitle.keyword",
"size": "10"
}
}
}
}
works.
What am I doing wrong ?
The problem is, that you're using Elasticsearch 7.11.
As you can see in the Release notes, they added the multi_terms feature in 7.12.0.
I used script_score to customize the scoring:
GET /customer/_search
{
"query": {
"function_score": {
"query": {
"match": {
"name": "Mark"
}
},
"script_score": {
"script": {
"lang": "painless",
"file": "test"
}
}
}
}
}
I set "file": "test", and put test.groovy file in config/scripts directory, but I got these error:
{
"error": {
"root_cause": [
{
"type": "illegal_argument_exception",
"reason": "[script] unknown field [file], parser not found"
}
],
"type": "illegal_argument_exception",
"reason": "[script] unknown field [file], parser not found"
},
"status": 400
}
[script] unknown field [file], parser not found! Why? Should I need to install some plugins?
Elasticsearch version : 6.2.3
Plugins installed: None
JVM version : 1.8.0_181
OS version: Ubuntu Linux 4.4.0-124-generic
File scripts have been removed in ES 6.0, you should now use stored scripts instead.
You can easily migrate your Groovy script to Painless.
First, store your script:
POST _scripts/test
{
"script": {
"lang": "painless",
"source": "Math.log(_score * 2)"
}
}
Then use it in your query:
GET /customer/_search
{
"query": {
"function_score": {
"query": {
"match": {
"name": "Mark"
}
},
"script_score": {
"script": {
"id": "test"
}
}
}
}
}
Sending post request to elastic search following is the post data
{
"query": {
"has_child" : {
"type" : "sometype",
"score_mode" : "sum",
"query" : {
"term" : {
"somefield" : "somevalue"
},
"function_score" : {
"script_score": {"script": "1"}
}
},
"inner_hits": {}
}
}
}
}
Getting response as malformed query
{
"error": {
"root_cause": [
{
"type": "parsing_exception",
"reason": "[term] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
"line": 10,
"col": 17
}
],
"type": "parsing_exception",
"reason": "[term] malformed query, expected [END_OBJECT] but found [FIELD_NAME]",
"line": 10,
"col": 17
},
"status": 400
}
Read documentation from this link: https://www.elastic.co/guide/en/elasticsearch/reference/5.4/query-dsl-has-child-query.html
Elasticsearch version: 5.4
You should make sure to wrap your term and function_score queries in a bool/filter query, like this:
{
"query": {
"has_child": {
"type": "sometype",
"score_mode": "sum",
"query": {
"bool": {
"must": [
{
"term": {
"somefield": "somevalue"
}
},
{
"function_score": {
"script_score": {
"script": "1"
}
}
}
]
}
},
"inner_hits": {}
}
}
}
Hi I am trying to update documents a elasticsearch which meets specific criteria. I am using google sense(chrome extension) for making request. The request that I am making is as shown below:
GET styling_rules2/product_line_filters/_update
{
"query": {
"filtered": {
"query": {
"bool": {
"should": [
{"term":{"product_line_attribute": "brand"}}
],
"minimum_should_match": 1
}
},
"filter": {
"term": {
"product_line_name": "women_skirts"
}
}
}
},
"script" : "ctx._source.brand=brands"
}
sample document is as shown below:
{
"product_line_attribute_db_path": "product_filter.brand",
"product_line_attribute": "brand",
"product_line_name": "women_skirts",
"product_line_attribute_value_list": [
"vero moda",
"faballey",
"only",
"rider republic",
"dorothy perkins"
]
}
desired result: update all the document which has product_line_attribute="brand" and product_line_name="women_skirts" to product_line_attribute="brands".
problem: I am getting the error as follows:
{
"error": {
"root_cause": [
{
"type": "search_parse_exception",
"reason": "failed to parse search source. unknown search element [script]",
"line": 18,
"col": 4
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "styling_rules2",
"node": "2ijp1pXwT46FN4on4-JPlg",
"reason": {
"type": "search_parse_exception",
"reason": "failed to parse search source. unknown search element [script]",
"line": 18,
"col": 4
}
}
]
},
"status": 400
}
thanks in advance!
You should use the _update_by_query endpoint and not _update. Also the script section is not correct, which is probably why you're getting a class_cast_exception.
Try this instead:
POST styling_rules2/product_line_filters/_update_by_query
{
"query": {
"filtered": {
"query": {
"bool": {
"should": [
{
"term": {
"product_line_attribute": "brand"
}
}
],
"minimum_should_match": 1
}
},
"filter": {
"term": {
"product_line_name": "women_skirts"
}
}
}
},
"script": {
"inline": "ctx._source.brand=brands"
}
}
below is my query, I want to change score calculation using function_score feature:
{
"size": 1,
"query":{
"function_score": {
"query": {
"bool": {
"must": [
{
"match": {
"messageText": "car"
}
}
]
}
},
"script_score" : {
"script" : "doc['time_views'].values[doc['time_views'].values.length-1]"
}
,
"boost_mode": "replace"
}
},
"from": 0
}
but I got this error response
{
"error": {
"root_cause": [
{
"type": "script_exception",
"reason": "failed to run inline script [doc['time_views'].values[doc['time_views'].values.length-1]] using lang [groovy]"
}
],
"type": "search_phase_execution_exception",
"reason": "all shards failed",
"phase": "query",
"grouped": true,
"failed_shards": [
{
"shard": 0,
"index": "datacollection",
"node": "TWeZV3R6Rq-WYQ2YIHjILQ",
"reason": {
"type": "script_exception",
"reason": "failed to run inline script [doc['time_views'].values[doc['time_views'].values.length-1]] using lang [groovy]",
"caused_by": {
"type": "illegal_argument_exception",
"reason": "No field found for [time_views] in mapping with types [message]"
}
}
}
]
},
"status": 500
}
some solutions says using quotation in "doc['time_views']" causes the problem when query has been send from command prompt tools. I don't know why!
I don't use any command prompt tools. I create the query in java code directly
EDIT
this is my index mapping:
"mappings": {
"message": {
"properties": {
"text": {
"type": "string"
},
"time_views": {
"type": "nested",
"properties": {
"backupTimestamp": {
"type": "long"
},
"views": {
"type": "integer"
}
}
}
}
}
}
}
I want to use "views" of last item of "time_views". so I try below scripts too, but each of them throw different error:
"doc['time_views.views'].values[doc['time_views.views'].values.length-1]"
error: java.util.ArrayList cannot be cast to java.lang.Number
"doc['time_views.views'].values[doc['time_views.views'].values.size()-1]"
error: failed to run inline script [doc['time_views.views'].values[doc['time_views.views'].values.size()-1]] using lang [groovy]
"doc['time_views'].values[doc['time_views'].values.size()-1].views"
error: failed to run inline script [doc['time_views'].values[doc['time_views'].values.size()-1].views] using lang [groovy]"
I'm really new in elasticsearch and groovy language. I didn't care about that "time_views" is nested Object, also I don't know syntax of groovy exactly, after some affort I found my mistakes and the solution:
{
"size": 1,
"query":{
"function_score": {
"query": {
"bool": {
"must": [
{
"match": {
"messageText": "car"
}
}
]
}
},
"script_score" : {
"script" : "doc['time_views.views'].values.get(doc['time_views.views'].values.size()-1)"
}
,
"boost_mode": "replace"
}
},
"from": 0
}
It's work as I expected
