If anyone here uses ixquick.com for searches rather than Google or Bing then the note on the homepage might of interest:
it's merging with startpage.comThe two are both out of the same stable but ixquick licences its search results from multiple search engines whereas startpage licences its search results from Google.
If you want to keep using the existing ixquick search formula then use ixquick.eu - and set the default language to English UK. You might also be able to use ixquick.co.uk, not sure whether that will continue to use existing engines or merge with Startpage.
