Anyone have some insight re: the following aggregation? I cannot access any
properties of the document in my script.
With the following query:
{
"query": {
"filtered": {
"filter": [],
"query": {
"bool": {
"must": [
{
"query_string": {
"fields": [
"title"
],
"query": "test"
}
}
]
}
}
}
},
"aggs": {
"my_field": {
"terms": {
"field": "my_field.name.raw",
"script": "doc['title'].value"
}
}
}
}
I get the following error:
QueryPhaseExecutionException[[index_name][2]: query[title:test],from[0],size
[10]: Query Failed [Failed to execute main query]]; nested:
PropertyAccessException[[Error: doc['title'].value: null] [Near : {... doc[
'title'].value ....}] ^ [Line: 1, Column: 1]]; nested:
InvocationTargetException; nested: ArrayIndexOutOfBoundsException;
I also try using _source.title, doc.get('title').value, and other
combinations of the doc['field'] syntax - none are working for me. Is there
a special nuance for using script within an aggregation? Am I missing
something obvious?
This fails on both ES 1.1.1 and 1.2.0.

Looks like I can answer my own question. From the docshttp://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations.html#_values_source
:
When both field and script settings are configured for the aggregation, the
script will be treated as a value script. While normal scripts are
evaluated on a document level (i.e. the script has access to all the data
associated with the document), value scripts are evaluated on the value
level. In this mode, the values are extracted from the configured field and
the script is used to apply a "transformation" over these value/s.
I was specifying a "field" param, meaning I was dealing with a value script.
