Hello everyone,
I have question to querys with parent-child-relationships.
When I do a bool query like this, where I only query fields of the child-type:
{
"query": {
"has\_parent": {
"type": "feature",
"score\_type": "score",
"query": {
"bool" : {
"should" : [ {
"query\_string" : {
"query" : "_costs_",
"default\_field" : "search.headline",
"use\_dis\_max" : true,
"default\_operator" : "and",
"allow\_leading\_wildcard" : true,
"boost" : 99.0
}
}]
}
}
}
}
}
With such a query I get no hits, but when I add another should-clause with a query over a parent fields, then I will get hits. But already with the first should clause, (theoretical) I have to become hits.
It looks weird. Only adding a query over a parent field helps to get a result.
Can anyone help me?
