Well, strictly speaking, you are right, with -x, the whole information
will be indexed.
But, since koha internally takes only iso2709 from zebra and not working
directly from marcxml then if your iso2709 is big... and your
biblionumber is at the end of your iso2709, then you will not be able to
get the biblionumber and therefore not be able to get the record.
And then, limiting the quantity of items indexed can be a workaround.
my 2 cents.
