I'm trying to run a query such as SELECT * FROM indexPeople WHERE info.Age > info.AgeExpectancy
Note the two fields are NOT nested, they are just json object
POST /indexPeople/_search
{
"from" : 0,
"size" : 200,
"query" : {
"bool" : {
"filter" : [
{
"bool" : {

"adjust_pure_negative" : true,
"boost" : 1.0
}
},
"_source" : {
"includes" : [
"info"
],
"excludes" : [ ]
}
}
However this query fails as
{

}
}
}
]
},
"status" : 400
}
Is there a way to achieve this?
What is the best way to debug it? I wanted to print the objects or look at the logs (which aren't there), but I couldn't find a way to do neither.
The mapping is:
{
"mappings": {
"_doc": {
"properties": {
"info": {
"properties": {
"Age": {
"type": "long"
},
"AgeExpectancy": {
"type": "long"
}
}
}
}
}
}
}
perhaps you already solved the issue. The reason why the query failed is clear:
"caused_by" : {
"type" : "illegal_state_exception",
"reason" : "A document doesn't have a value for a field! Use doc[<field>].size()==0 to check if a document is missing a field!"
}
Basically there is one or more document that do not have one of the queried fields. So you can achieve the result you need by using an if to check if the fields do indeed exists. If they do not exist, you can simply return false as follows:
{
"script": """
if (doc['info.Age'].size() > 0 && doc['info.AgeExpectancy'].size() > 0) {
return doc['info.Age'].value > doc['info.AgeExpectancy'].value
}
return false;
}
"""
I tested it with an Elasticsearch 7.10.2 and it works.
What is the best way to debug it
That is a though question, perhaps someone has a better answer for it. I try to list some options. Obviously, debugging requires to read carefully the error messages.
PAINLESS LAB
If you have a pretty recent version of Kibana, you can try to use the painless lab to simulate your documents and get the errors quicker and in a more focused environment.
KIBANA Scripted Field
You can try to create a bolean scripted field in the index pattern named condition. Before clicking create remember to click "preview result":
MINIMAL EXAMPLE Create a minimal example to reduce the complexity.
For this answer I used a sample index with four documents with all possible cases.
No info: { "message": "ok"}
Info.Age but not AgeExpectancy: {"message":"ok","info":{"Age":14}}
Info.AgeExpectancy but not Age: {"message":"ok","info":{"AgeExpectancy":12}}
Info.Age and AgeExpectancy: {"message":"ok","info":{"Age":14, "AgeExpectancy": 12}}

{
"virtual": "/testss/3-1.pdf",

I am trying to pass the file value "3-1" into the following script and then conditionally either return the value or divide it by 100:

}
"""

What should I do differently here?
I tried referencing File: "3-1" with doc['file'].value in the script...doesnt seem to be working.
This ended up working for me:
POST my-index-000001/_update_by_query/ { "script": {
"lang": "painless",
"source": "ctx._source.caseno=Arrays.asList(ctx._source.virtual.splitOnToken('/'))[1];ctx._source.file=Arrays.asList(Arrays.asList(ctx._source.virtual.splitOnToken('/'))[2].splitOnToken('.'))[0];List
i=Arrays.asList(Arrays.asList(Arrays.asList(ctx._source.virtual.splitOnToken('/'))[2].splitOnToken('.'))[0].splitOnToken('-'));if
(i.length==1){ctx._source.mynewfield=Float.parseFloat(i[0]);}if
(i.length==2){ctx._source.mynewfield=Float.parseFloat(i[0])+Float.parseFloat(i[1])/100}"
} }
Im trying to run the following script
POST /data_hip/_update/1638643727.0
{
"script":{
"source":"ctx._source.avgmer=4;"
}
}
But I am getting the following error.
{
"error" : {
"root_cause" : [
{
"type" : "mapper_parsing_exception",
"reason" : "failed to parse field [#timestamp] of type [date] in document with id '1638643727.0'. Preview of field's value: '1.638642742E12'"

this is strange because on queries (not updates) the date time is parsed fine.
The timestamp field mapping is as follows
"#timestamp": {
"type":"date",
"format":"epoch_millis"
},
I am running elasticsearch 7+

Im not running an ingest pipeline
The problem is the scientific notation, the 'E12' suffix, being in a field that ES is expecting to be an integer.
Using this reprex:
PUT so_test
{
"mappings": {
"properties": {
"ts": {
"type": "date",
"format": "epoch_millis"
}
}
}
}
# this works
POST so_test/_doc/
{
"ts" : "123456789"
}
# this does not, throws the same error you have IRL
POST so_test/_doc/
{
"ts" : "123456789E12"
}
I'm not sure how/where those values are creeping in, but they are there in the document you are passing to ES.
I'm working with elasticsearch painless more than two years.
These days I found out a weird problem with naming painless variable as "Number". When "Number" (first letter is uppercase) is used in painless script, error occured.
I sucessfully reproduce this scenario.
I'm using elasticsearch version 6.8.
curl -X POST "http://localhost:9201/logs-my_app-default/_search?size=2&pretty" -H 'Content-Type: application/json' -d '{"_source": ["-1"], "script_fields": {"SCRIPT_FLAG": {"script": {"lang": "painless", "source": " def Number = 0; "}}}}'
The problem comes from:
def Number = 0;
Thrown error is:
"error" : {
"root_cause" : [
{
"type" : "script_exception",
"reason" : "compile error",
"script_stack" : [
" def Number = 0; ",
" ^---- HERE"
],
"script" : " def Number = 0; ",
"lang" : "painless"
}
],
"type" : "search_phase_execution_exception",
"reason" : "all shards failed",
"phase" : "query",

"index" : "logs-my_app-default",
"node" : "9jBNNKjdSIO6I8UH_HLVRw",
"reason" : {
"type" : "script_exception",
"reason" : "compile error",
"script_stack" : [
" def Number = 0; ",

],
"script" : " def Number = 0; ",
"lang" : "painless",
"caused_by" : {
"type" : "illegal_argument_exception",
"reason" : "invalid sequence of tokens near ['Number'].",
"caused_by" : {
"type" : "no_viable_alt_exception",
"reason" : null
}
}
}
}
]
},
"status" : 500
}
This is happening on any elasticsearch index for me, es version 6.8
To be more precise, this is the index used in scenario shown here.
curl -X POST "localhost:9201/logs-my_app-default/_doc?pretty" -H 'Content-Type: application/json' -d'
{
"#timestamp": "2099-05-06T16:21:15.000Z",
"event": {
"original": "192.0.2.42 - - [06/May/2099:16:21:15 +0000] \"GET /images/bg.jpg HTTP/1.0\" 200 24736"
}
}
'
Mapping as well:
curl -X GET "localhost:9201/logs-my_app-default/_mapping?pretty"
{
"logs-my_app-default" : {
"mappings" : {
"_doc" : {
"properties" : {
"#timestamp" : {
"type" : "date"
},
"event" : {
"properties" : {
"original" : {
"type" : "text",
"fields" : {
"keyword" : {
"type" : "keyword",
"ignore_above" : 256
}
}
}
}
}
}
}
}
}
}
Any variant of string "Number" as "number" (all lowercase) works.
"Numb", "Numbe" works as well..
Any help?
Thank you.
SOLUTION:
Almost all of the casesensitive keywords mentioned here are throwing the same error as shown above.
Good practice for me is to use underscore as prefix when creating painless variable with same name as elasticsearch field ..
For example:
def _Number = 0; // instead of def Number = 0,
def _Void = 0; // instead of def Void = 0; ,
def _System = 0; // instead of def System = 0; ..
The Painless scripting language is very similar to the Java programming language, compiles directly into JVM bytecode, and its API borrows a lot from the Java API, namely the Number class.
For this reason, you cannot use Number as an arbitrary variable identifier.
I've tried to use update api. I've inserted a document which contains a list.
INSERT:
curl -XPOST "http://localhost:9200/t/t/1" -d'
{
"hobbies(first)" : ["a", "b"]
}'
UPDATE QUERY:
curl -XPOST localhost:9200/t/t/1/_update?pretty -d '{ "script" : {
"inline": "ctx._source.hobbies(first).add(params.new_hobby)",
"params" : {
"new_hobby" : "c"
}
}
}'

When I've tried to update list, I've got error above. I've realized that when I removed part with brackets('(first)') from my field's name, it's working. How can I prepare an update query with a field name with brackets?
Thanks in advance.
this is a horrible convention for field names, just stick with alphanumerics (please keep in mind, that someone after you has to maintain this, so it would be so much nicer to work with cleaner data in Elasticsearch). You can try ctx.source['hobbies(first)']
I have the following sample mappipng:
{
"book" : {
"properties" : {
"author" : { "type" : "string" },
"title" : { "type" : "string" },
"reviews" : {
"properties" : {
"url" : { "type" : "string" },
"score" : { "type" : "integer" }
}
},
"chapters" : {
"include_in_root" : 1,
"type" : "nested",
"properties" : {
"name" : { "type" : "string" }
}
}
}
}
}
I would like to get a facet on number of reviews - i.e. length of the "reviews" array.
For instance, verbally spoken results I need are: "100 documents with 10 reviews, 20 documents with 5 reviews, ..."
I'm trying the following statistical facet:
{
"query" : {
"match_all" : {}
},
"facets" : {
"stat1" : {
"statistical" : {"script" : "doc['reviews.score'].values.size()"}
}
}
}
but it keeps failing with:
{
"error" : "SearchPhaseExecutionException[Failed to execute phase [query_fetch], total failure; shardFailures {[mDsNfjLhRIyPObaOcxQo2w][facettest][0]: QueryPhaseExecutionException[[facettest][0]: query[ConstantScore(NotDeleted(cache(org.elasticsearch.index.search.nested.NonNestedDocsFilter#a2a5984b)))],from[0],size[10]: Query Failed [Failed to execute main query]]; nested: PropertyAccessException[[Error: could not access: reviews; in class: org.elasticsearch.search.lookup.DocLookup]
[Near : {... doc[reviews.score].values.size() ....}]
^
[Line: 1, Column: 5]]; }]",
"status" : 500
}
How can I achieve my goal?
ElasticSearch version is 0.19.9.
Here is my sample data:
{
"author" : "Mark Twain",
"title" : "The Adventures of Tom Sawyer",
"reviews" : [
{
"url" : "amazon.com",
"score" : 10
},
{
"url" : "www.barnesandnoble.com",
"score" : 9
}
],
"chapters" : [
{ "name" : "Chapter 1" }, { "name" : "Chapter 2" }
]
}
{
"author" : "Jack London",
"title" : "The Call of the Wild",
"reviews" : [
{
"url" : "amazon.com",
"score" : 8
},
{
"url" : "www.barnesandnoble.com",
"score" : 9
},
{
"url" : "www.books.com",
"score" : 5
}
],
"chapters" : [
{ "name" : "Chapter 1" }, { "name" : "Chapter 2" }
]
}
It looks like you are using curl to execute your query and this curl statement looks like this:
curl localhost:9200/my-index/book -d '{....}'
The problem here is that because you are using apostrophes to wrap the body of the request, you need to escape all apostrophes that it contains. So, you script should become:
{"script" : "doc['\''reviews.score'\''].values.size()"}
or
{"script" : "doc[\"reviews.score"].values.size()"}
The second issue is that from your description it looks like your are looking for a histogram facet or a range facet but not for a statistical facet. So, I would suggest trying something like this:
curl "localhost:9200/test-idx/book/_search?search_type=count&pretty" -d '{
"query" : {
"match_all" : {}
},
"facets" : {
"histo1" : {
"histogram" : {
"key_script" : "doc[\"reviews.score\"].values.size()",
"value_script" : "doc[\"reviews.score\"].values.size()",
"interval" : 1
}
}
}
}'
The third problem is that the script in the facet will be called for every single record in the result list and if you have a lot of results it might take really long time. So, I would suggest indexing an additional field called number_of_reviews that should be populated with the number of reviews by your client. Then your query would simply become:
curl "localhost:9200/test-idx/book/_search?search_type=count&pretty" -d '{
"query" : {
"match_all" : {}
},
"facets" : {
"histo1" : {
"histogram" : {
"field" : "number_of_reviews"
"interval" : 1
}
}
}
}'
