Difference between "more results" and "omitted results"

From 4000 to 38000

[Lexur]

When I do a search with the allinurl operator and www.mydomain.com i get these results:

====================================================

Site Title-
Site description ...
www.mydomain.com/ - 18k - Cached - Similar pages

Good and very popular and linked article title-
Meta descripction from the page.
www.mydomain.com/dir/article.htm - 13k - Cached - Similar pages
[ More results from www.mydomain.com ]

In order to show you the most relevant results, we have omitted some entries very similar to the 2 already displayed.
If you like, you can repeat the search with the omitted results included.

======================================================

If I click in "More results from www.mydomain.com" I have

"Results 1 - 100 of about 4,230 from www.mydomain.com for allinurl:www.mydomain.com. (0.07 seconds)"

...but if I click on "repeat the search with the omitted results included." I have

"Results 1 - 100 of about 38,400 for allinurl:www.mydomain.com"

I checked the first 1000 results and I didn't see any kind of results out of my own site. Where are the remaining 34,000?

By the way, this PR6 site has around 6000 pages is four years old.
