Amount of writes during index creation

I have had a problem report from a Recoll user about the amount of writes
during index creation.

The issue is that the index is on SSD and that the amount of writes is
significant compared to the SSD life expectancy (index size > 250 GB).

>From the numbers he supplied, it seems to me that the total amount of block
writes is roughly quadratic with the index size.

First question: is this expected, or is Recoll doing something wrong ?

Second question: for now, the user is creating multiple indexes, and
querying them in parallel. This reduces the amount of writes by a factor of
three. Is this the best approach, are there other possibilities ?
