Except for the big volume queries, I don't remember ever seeing ten solid results for most searches. That is the ideal, certainly, assuming that ten good results exist. The reality is that machine intelligence is not yet that good, and there's a lot of dreck out there muddying the water.
A lot of my searches are either for pages that I know exist or technical questions. Both of those query types had been getting mighty rough in recent months, and both of them seem to have improved for me in March.
Finding pages that I remember from months ago is still a bit challenged because the "freshness" dial seems to be cranked up too high for my taste, but it has at least become possible again. For a few months it often felt hopeless.
