I'm using dynamic mapping to index a bunch of documents with numbers in some fields. Some of these numbers are integers and some have decimal points. If the first point I send to an index happens to have an integer in a field, then Elasticsearch maps that field as a long in that index. So then any subsequent points with decimals in that field get rounded down, and all the math I do on those documents comes out wrong. I don't want this. Can I tell Elasticsearch that I'm not intereseted in longs and only want doubles in my documents?

Have you tried creating a static mapping instead?

I don't know what the fields are gonna be in advance, just that some fields will have numbers that might be integers or doubles. So I'm looking at [https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-root-object-type.html#\_dynamic\_templates](https://www.elastic.co/guide/en/elasticsearch/reference/current/mapping-root-object-type.html#_dynamic_templates) and thinking that a dynamic template like
```auto
{
"long_smasher": {
"match": "*",
"match_mapping_type": "long",
"mapping": {
"type": "double"
}
}
},
```
will do the job.
