Normally in most cases such as yours, reindexing Spotlight will correct the problem.  Try it again.
This seems to be a common problem with Yosemite.
If that does not correct the problem, you may try SMC and PRAM resets:
(This is a guess on my part.  No harm can come to the MBP performing these resets.)
The last option is a reinstall of the OSX.
May I assume that the overall amount of data is correct?  If not, then we will have to look at OmniDiskSweeper and Grand Perspective.
