Hi,
i'm having issue filtering by script on a nested array.
this is my sample data and mapping:
{
"id" : "123",
"messages" : [
{
"level" : "error",
"timestamp" : "01/02/2021",
"message" : "event1"
},
{
"level" : "error",
"timestamp" : "01/02/2021",
"message" : "event2"
},
{
"level" : "trace",
"timestamp" : "02/02/2021",
"message" : "event3"
}
]
}
mapping:
{
"mappings" : {
"properties" : {
"messages" : {
"type" : "nested",
"properties" : {
"level" : {
"type" : "keyword"
},
"message" : {
"type" : "text"
},
"timestamp" : {
"type" : "date",
"format" : "dd/MM/yyyy"
}
}
},
"id" : {
"type" : "keyword"
}
}
}
}
here is a sample query to try and find documents with at leaser 2 error messages:
{
"query": {
"bool": {
"filter": {
"script": {
"script": {
"source": """
int counter = 0;
for (def event : doc['messages'].value) {
if (event.level.equals("error")) { counter++; }
}
return counter > 1;
""",
"lang": "painless"
}
}
}
}
}
}
but i' getting the following error: No field found for [messages] in mapping with types .
if i'm trying to do any filtering on id field (which is not nested) everything works fine.
I could not find in the documentation if this is supported or not and if it does - then how to apply such logic.
I'm using version 7.10
