elasticadhocstats

The command elasticadhocstats queries Elasticsearch with a DSL query provided in the search command itself. The command is helpful while testing a DSL query and for quick checks. Queries run by elasticadhocstats return aggregated data as results. Therefore, the data is formatted as a table. Timestamp fields and dynamic timestamp parsing are available with the command even though the returned data does not need to be time-series data. Due to the JSON nature of DSL queries, the command usually gets large and is hard to read. Therefore, if you need to repeat any DSL queries, the usage of elasticquerystats is strongly advised.

timestamp_field	yes	string	field in Elasticsearch results containing the events timestamp
