So, I want to use the tstats command. It's super fast and efficient. But not if it's going to remove important results. Any record that happens to have just one null value at search time just gets eliminated from the count. That's important data to know.
It looks like only those fields we can use with tstats which is extracted at time of indexing, as I am running walklex on _internal index bucket and I can see component field in tsidx file so we can use that in tstats but not other fields like bytes from _internal index with above query (If we use datamodel then we can definitely use that 🙂 but without datamodel I think tstats limits with only fields which are extracted at index time)
