Factor parameter in Date Histogram aggregation not accepted

[junckritter]

According to documentation (http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-datehistogram-aggregation.html#_factor_2) date histogram aggregation should accept factor parameter. But using it results in

Parse Failure [Unknown key for a VALUE_NUMBER in [agg]: [factor].]

Query example:

"aggs" : { 
    "registration": {
        "date_histogram": {
            "field": "registration_date",
            "interval": "day", 
            "format": "dd-MM-yyyy",
            "min_doc_count": 0,
            "extended_bounds": {
                "min": "now/d-30d",
                "max": "now/d"
            },
            "factor": 1000  
        }
    }
}

Without factor, query works just fine.

Using version 1.1.2, but looking to source of master (https://github.com/elasticsearch/elasticsearch/blob/master/src/main/java/org/elasticsearch/search/aggregations/bucket/histogram/DateHistogramParser.java#L124), factor is not used there neither.

I'm running into the same issue. Any word on this as it's causing some parsing errors on my end which means I have to use facets for now.

@uboness it looks like factor isn't supported in date histo aggs, even though it is documented:
http://www.elasticsearch.org/guide/en/elasticsearch/reference/current/search-aggregations-bucket-datehistogram-aggregation.html#_factor_2

[clintongormley]

@jpountz are there plans to support factor or in date_histos or should we drop it? I'd be in favour of dropping it. date histos should be run on date fields.

[jpountz]

@clintongormley I would be +1 on dropping it as well and requiring the field to be either a date or unmapped in order for a date aggregation to succeed.

Agreed - closing
