What is the final sort that breaks ties of default sorts or if there is no sort specified?

-----Question-----
What is the final tie breaker for the following types of sorts?

1. Default sort
2. When there is no default sort or explicit sort or relevance ranking selected
3. Final relevance ranking module in a strategy.


-----Answer-----
For cases 1 and 2, the final sort will be determined by a random but consistent order, with records ranked by a "record ID" assigned during indexing. This value is consistent from query to query in a given index set, but may change after each baseline or partial update.

For case 3, the ties in the final module of a relevance ranking strategy are broken by the default sort (which in turn breaks ties using the "record ID" sort order).

There is no way to manipulate the record ID assignment.

One way to manipulate sort order is to add an additional value to every record which can be used to break ties, effectively creating a synthetic key and adding it to the end of all sorts.
