I'm a bit perplexed by the occasional report of the search function being "worse than before", or "impossible to use" etc. I know it has changed, but to me it seems (a) more richly featured and (b) more successful in actually finding yer stuff.
As a lickle suggestion, maybe those who are having trouble could present their information as follows:
1. If it doesn't offer the method of searching that you want, then state the method of searching that you want that it doesn't offer.
or:
2. If it searches how you want, but doesn't find what you need, then give an example of the search attributes that you're using.
or:
3. If it finds what you need, but doesn't present it in the manner you like, then give an example of the search attributes AND the manner of results presentation that you would like.
or:
4. Just whinge and moan and bleat and whinge some more and stomp your feet and have a little tantrum and berate someone who's doing their best to provide what you want but isn't being given much in the way of useful feedback.
