描述

In a given content cluster, using the schema, let the user easily create a selection string.

Then, add ability to run a visit using this, outputting how far into document space it is and how many documents are returned so far. This simplifies the process to develop a selection string and test it before deploying it - i.e. how many docs / fraction is kept when running the visit with the selection

visit can dump IDs only to speed up

研究方向
Investigate how selection strings are currently used in Vespa, particularly in the document API. Look at existing code for visit operations to understand how to integrate a tester that outputs document count and fraction. The issue suggests dumping IDs to speed up, so explore the visit API and see how to extend it with a dry run mode.
