Site Tool : Change in reporting similar pages

Is this a new feature?

[Whitey]

In the last few days, all of our 8 sites are now reduced from the full page no. of results [ approx [ 70,000 ] to only show:

Results 1 - 1 of about 260 from oursite.com

with only 2 page results and a note:

In order to show you the most relevant results, we have omitted some entries very similar to the 1 already displayed.
If you like, you can " repeat the search with the omitted results included. "

When clicking on the "repeat .... link " it shows most of the pages.

Is anyone else experiencing this?

What does this say about Google's interpretation of the site's pages?

Actually it's throwing up a lot of supplementals for us which i wouldn't expect, even though the 1 to 260 has gone.

Does anyone else have a clue if it's working properly?
