The search results estimates that appear on the Advanced Search query page are not accurate when searching by update date. In some cases they are drastically different because the estimates are calculated using indexes and not the search itself. To calculate the estimate for update date we count all the profiles where any update date meets the search criteria and any update date events are significant. In the search we include the profile only if the update date that meets the search criteria is also a significant event. We do it this way because it is much faster to estimate using indexes than the actual search. When you execute the search by clicking the ‘Show Results’ button, you will see the correct profile results on the results page.
