Unfortunately no. What you can do is search specific bit rates, eg: 192 kbps or 320 kbps using the Audio search & bit rate search criteria. Or else, as I do, I double click the top of the bit rate column so it arranges the bitrates with the largest at the top. (However those with no bit rate listed are listed before these.) Personally I generally use the ANy Type search & then filter them using the Audio & then artist filters (though keep in mind sometimes some artists may be in the results but because they don't have id3 tags, they don't show under artist.)
