Because the Index Fragmentation collection by default runs only once a day (at 4:15AM), you won’t see the reflected changes in Spotlight until the next day. This by design since this collection can cause timeout issues.
You can view/edit the scheduled time of this collection in Spotlight by going to Configure toolbar and selecting ‘Scheduling’ icon. In this dialogue, first choose your connection name from drop-down list on the top. Then scroll down the list of collections to ‘Fragmentation Overview’ and edit it. Disable ‘Factory Settings’ option to change time interval of this collection.
Hope that helps.
