Is timestamp field in a logentry of logfile also indexed (ie, made searchable by means of inverted index data structure) while storing time series data like logs into an index/data stream,  
provided we are not explicitly mentioning about indexing by means of the dynamic parameter(like dynamic=true/false/runtime)?

In what all other places/data structures a timestamp field in a log is stored, like \_source, docvalues, field cache etc.

thanks and regards

Any field, by default, is indexed and treated the same in Elasticsearch.
