How to index percolator queries containing filters on inner objects? - elasticsearch

Question

Using Elasticsearch 2.1.1
I have documents with inner objects:
{
"level1": {
"level2": 42
}
}
I want to register percolator queries applying filters on the inner property:
$ curl -XPUT http://localhost:9200/myindex/.percolator/myquery?pretty -d '{
"query": {
"filtered": {
"filter": {
"range": {
"level1.level2": {
"gt": 10
}
}
}
}
}
}'
It fails because I don't have a mapping:
{
"error" : {
"root_cause" : [ {
"type" : "query_parsing_exception",
"reason" : "Strict field resolution and no field mapping can be found for the field with name [level1.level2]",
"index" : "myindex",
"line" : 1,
"col" : 58
} ],
"type" : "percolator_exception",
"reason" : "failed to parse query [myquery]",
"index" : "myindex",
"caused_by" : {
"type" : "query_parsing_exception",
"reason" : "Strict field resolution and no field mapping can be found for the field with name [level1.level2]",
"index" : "myindex",
"line" : 1,
"col" : 58
}
},
"status" : 500
}
So I start again, but this time I add a mapping template before:
curl -XDELETE http://localhost:9200/_template/myindex
curl -XDELETE http://localhost:9200/myindex
curl -XPUT http://localhost:9200/_template/myindex?pretty -d 'x
{
"template": "myindex",
"mappings" : {
"mytype" : {
"properties" : {
"level1" : {
"properties" : {
"level2" : {
"type" : "long"
}
}
}
}
}
}
}
'
I try to register my percolator query again:
curl -XPUT http://localhost:9200/myindex/.percolator/myquery?pretty -d '{
"query": {
"filtered": {
"filter": {
"range": {
"level1.level2": {
"gt": 10
}
}
}
}
}
}'
And now it succeeds:
{
"_index" : "myindex",
"_type" : ".percolator",
"_id" : "myquery",
"_version" : 1,
"_shards" : {
"total" : 1,
"successful" : 1,
"failed" : 0
},
"created" : true
}
And I can see the mapping that has been created:
curl http://localhost:9200/myindex/_mapping?pretty
{
"myindex" : {
"mappings" : {
".percolator" : {
"properties" : {
"query" : {
"type" : "object",
"enabled" : false
}
}
},
"mytype" : {
"properties" : {
"level1" : {
"properties" : {
"level2" : {
"type" : "long"
}
}
}
}
}
}
}
}
Now my problem is that I also need to perform searches on my percolator queries and the default percolate mapping doesn’t index the query field.
So I start again, this time specifying in my mapping template that I want percolator queries to be indexed (note "enabled": true):
curl -XPUT http://localhost:9200/_template/myindex?pretty -d '
{
"template": "myindex",
"mappings" : {
".percolator" : {
"properties" : {
"query" : {
"type" : "object",
"enabled" : true
}
}
},
"mytype" : {
"properties" : {
"level1" : {
"properties" : {
"level2" : {
"type" : "long"
}
}
}
}
}
}
}
'
I try to register my percolator query again:
curl -XPUT http://localhost:9200/myindex/.percolator/myquery?pretty -d '{
"query": {
"filtered": {
"filter": {
"range": {
"level1.level2": {
"gt": 10
}
}
}
}
}
}'
But now I get an error:
{
"error" : {
"root_cause" : [ {
"type" : "mapper_parsing_exception",
"reason" : "Field name [level1.level2] cannot contain '.'"
} ],
"type" : "mapper_parsing_exception",
"reason" : "Field name [level1.level2] cannot contain '.'"
},
"status" : 400
}
How can I create and index a percolator query matching an inner property?
