Is there any way to monitor the progress (ideally in percent) of a (full) crawl in SharePoint?
Update:
I know I can monitor the progression by viewing the crawled items, but I want to find a way to have a real progress indicator, because having to do a full crawl on a large productive system with no indication of how long it might take and how much has already been done is basically unacceptable.
One very rough approach is to get the item count of the last crawl, track the current crawl's item count as mentioned and estimate progress by comparing those two.
