Serach engine problems since the latest Update

[DadoO]

Another problem seems to occured after the latest update

If you do a search on your site, let's say you have three pages of results
Click on the second page, and there it goes into a sausage shape and displays all the products on the site

Example of the links in question after the search on the second page

Example after the search

*******/boutique/results,1-20?keyword=ULN2803&limitstart=0&option=com_virtuemart&view=category&virtuemart_category_id=0

Now clik on the secpond page button

******/boutique?start=20

Hum very strange the link

What happens
ISit easy to solve this?
