Are numbers: integer, long, float etc… in Elasticsearch not_analyzed?

Question

Using Elasticsearch 1.4.3

I went through the docs but I\'m not sure exactly. But I figure that integer, long, float, double etc... are indexed as not_analyzed by Luc

Answer 1

From this link you have this statement:

The other simple types (such as long, double, date etc) also accept the index parameter, but the only relevant values are no and not_analyzed, as their values are never analyzed.

Answer 2

Simple, non-string types (such as long, double, date etc) are not analyzed by default.

That's why you can omit "index": "not_analyzed" in the following mapping definition:

...
"mappings": {
    "properties": {
        "price": {
            "type": "long",
            "index": "not_analyzed"
        }
    }
}
...

But you might decide to not index this field at all:

...
"mappings": {
    "properties": {
        "price": {
            "type": "long",
            "index": "no"
        }
    }
}
...

As a result this field will not be searchable.
