I recently was using a Smart Collection to review selects and I would come up with different results as I openend and closed folders that were a part of Smart Collection file base. Its as if my files hadn't been correctlty indexed or were not being indexed until I opened a folder and selected a file to view.
Is there a way to make sure my files are being indexed or is reseting the Prefs the only way to do this?
You can either visit each folder and wait until the spinning arrow is finished indexing, which takes awhile.
Another way is to do a search at the start of the directory (it searches down) and check include non-indexed files. You can see what folder it is on in the lower left corner. THis will take awhile also, but you can do the search when you are not using the computer and just let it run. If you have to stop it before it is done, note where it is at and then start search there next time.
