'''
In this example, we select calculations/upload by query and iterate through all
uploads in parallel, reading the uploads in full to extract some information for each
calculation.
The motivation behind this is that the selective access of sections in an archvie might
be slow. If something is read from almost all calculations, it might be faster to
sequentially read all of the upload's archive file.
This is not an API example, but directly accesses archive files.

In this example, we go through many uploads in parallel to extract information from
certain calculations.
The motivation behind this is that the selective access of sections in an archvie might
be slow. If something is read from almost all calculations, it might be faster to
sequentially read all of the upload's archive file.
This is not an API example, but directly accesses archive files. Specifically, we
try to read all fingerprints for upload/calc/material combinations read from an
input file. The fingerprint data gets writting to an output file.

This examplefies how to send raw queries to elasticsearch.
Specifically this will read all materials with fingerprints from the search engine
and store them in a local file. We use composite aggregations with after-based
pagination.
