How can I define a data range to be imported for elasticsearch

Let's suppose a sql _where_ clause:

```sql
where (year = 2021 and month = 1 and day>=1)
and (year = 2021 and month = 1 and day<=31)
```
How can I define a data range to be imported to elasticsearch with `abc`?

- [x] This issue has a description.

No files, tests, or command entry points are named. Start with the SQL WHERE-clause example and clarify how abc's Elasticsearch import should express the date range; done means an agreed, documented way to import only the requested records, with verification of the resulting range.
