Libby9, while I understand that some of you are finding the change difficult, I really don't think you're being completely fair to Ancestry?
The "new" search was introduced in 2008 - so you've had 6 years to try it out and get used to it.
I think the mistake that Ancestry made was to keep the "old" search available for all that time!
Those of us who have been using the "new" search for some time seem to get on with it perfectly OK?
Like anything new, it just takes a little time to get used to! 
I do rather have to take issue with this KGarrad.
Ancestry may have introduced
A new search some years ago, and allowed the old search to be used if preferred, but are you saying that what appeared last week is EXACTLY the format which you have been using all this time? 6 years?
I have also been using the new search as default, but not that which is placed before me now.
I have been following comments from Ancestry users worldwide, and can tell you that it is more than a few who are complaining of the many aspects that just don't work. Some of these subscribers have been members for a few years only, so have never used the 'old' search.
I quote.
"Those of us who have been using the "new" search for some time seem to get on with it perfectly OK?"Is this a question for all users? It does have question mark at the end, but it seemed you were really making a statement, and that anyone not happy would just have to 'suck it up'. Rather in the vein of Ancestry's sentiments I think.
I agree with Libby. Ancestry really should listen. Shortsighted not to.
