Now I am on the computer, not the droid, I can give you some figures.
Probe TT in QSearch = Off
Score : +0.28
Depth : 14/1
Time : 00:00:30
Nodes : 6600000
N/sec : 217702
Hash %: 78.5
1. Nc3 Nc6 2. Nf3 Nf6 3. d4 e6 4. e4 d5
Probe TT in QSearch = On
Score : +0.30
Depth : 14/1
Time : 00:00:31
Nodes : 4780000
N/sec : 151186
Hash %: 65.6
1. Nc3 Nc6 2. Nf3 Nf6 3. d4 d5 4. Qd3 g6 5. Bf4 Nh5 6. Be5
So less nodes (a quarter reduction), and I get a longer PV. But NPS takes a large hit (-30%), and the hash takes longer to fill (I used 16MB).
I have Probe TT in QSearch set to Off, because I think that the Fruit hash probe was not designed for use in QSearch.
