I'm using PB4, just released today, and Spotlight is acting like the one in Yosemite. I can't do the new searches (Weather, Sports, etc...). I filed a bug report.
It has been an ongoing issue wth the betas. File a report OP and be patient.
Also, there is no need to create three threads on the same subject. There has been threads on this issue before you posted. Try using the forum search.
