=== Or Filter

A filter that matches documents using `OR` boolean operator on other
queries. Can be placed within queries that accept a filter.

[source,js]
--------------------------------------------------
{
    "filtered" : {
        "query" : {
            "term" : { "name.first" : "shay" }
        },
        "filter" : {
            "or" : [
                {
                    "term" : { "name.second" : "banon" }
                },
                {
                    "term" : { "name.nick" : "kimchy" }
                }
            ]
        }
    }
}

==== Caching

The result of the filter is not cached by default. The `_cache` can be
set to `true` in order to cache it (though usually not needed). Since
the `_cache` element requires to be set on the `or` filter itself, the
structure then changes a bit to have the filters provided within a
`filters` element:

[source,js]
--------------------------------------------------
{
    "filtered" : {
        "query" : {
            "term" : { "name.first" : "shay" }
        },
        "filter" : {
            "or" : {
                "filters" : [
                    {
                        "term" : { "name.second" : "banon" }
                    },
                    {
                        "term" : { "name.nick" : "kimchy" }
                    }
                ],
                "_cache" : true
            }
        }
    }
}
