well I guess whatever they do they're screwd. when the original search was made available the complaints were:
it doesn't give enough search results
it doesn't search very well
I can never find what I'm looking for
I did search, but I don't think it's working properly
I don't like the way it searches, why can't it be like this
So then they were told to use google in addition to the search, but the complaints were always the same in addition to:
Can someone teach me how to use the google search, because I don't like the WP search facility
Google gives better results why isn't that included?
So here we are, and it's now using google, it's actually better in that gives more results - something users wanted. If the USER is more specific about their search, the search will be better, and although it doesn't have the WP layout, it's still searching WP
They just can't win I guess :)
