When I check backlinks to my domain using linkdomain command, Yahoo returns ~120 results. When I click on the second page of the results Yahoo says "11-20 of about 120" and so on. But for some reason starting from the page no. 7 the SE changes its mind and returns "61-70 of about 1,500". Then I can browse the results further up to the page no. 15 where I get the usual "omitted similar results" note. Searching with the omitted results included reveals all 1,500 links.
Did anybody notice this behavior? Is it a bug, or may be Yahoo is following Google and will show only a tiny portion of backlinks in the future?
