Is there a way to easily check for the existence of a key and subsequently
access keys in complex object (nested, maybe at times 3 levels deep
unfortunately)
simplified example doc:
{
"level1" : {
"level2" : {
"links" : ["http://bit.ly/abc";, "http://bit.ly/abc";, "http://bit.ly/def";,
"http://bit.ly/ghi";]
}
},
"title" : "test123"
}
This doesn't seem to work (form what I can tell it never finds the key
level1.level2.links even when it does exist)
"script" : "if (ctx._source.containsKey('level1.level2.links') )
{ctx._source.links_url_count = ctx._source['level1.level2.links''].size() }
else { ctx._source.links_url_count = 0 }"
Simple keys work though like ctx._source.containsKey('title')
Does it require intermediate checks for every level (which could be a messy
script)?
