I would like to know if elasticsearch considers empty string as null value, but based on my mapping shown below, I don't see that it is doing that. How can I make elasticsearch consider empty string as a null
and index using the value provided by null_value
. My mapping is shown below:
{
"mapping": {
"my_typee": {
"properties": {
"autoRank": {
"type": "integer",
"null_value": 0,
"store": true,
"index": "analyzed"
}
}
}
}
}
Thanks in advance.

Elasticsearch does not index empty strings. In your case your field is actually not string but an integer of type. And null_value
option is actually does what you want to do. You dont need to do anything extra.
