Technically, UltraSearch does not maintain any index or database of files like Everything or Windows Search. Just right click any folder, select UltraSearch and search within that folder. The best feature of UltraSearch is that it will add a context menu item which can be used to search in a particular folder instantly. You can use wildcards and other operators like double quotes for exact matching, regular expressions. UltraSearch comes with a pretty good advanced search. It comes with almost the same interface as Search Everything with an exception of selecting drives to search in and using exclude filters.

It has all the functionalities, including advanced search, to cater to my search needs in my local computer. I have been able to find the exact files that I was looking for using this utility. My search experience with Search Everything has been great. However, wildcards are not supported by the app. Search Everything does not include any advanced search functionality but you can use advanced search operators right within the search field. Your first search will be somewhat slower (due to the indexing), but after that, Search Everything will give instant results. I bet you will not even know it when it is building its database. Search Everything will build an index of all the files and folders in your computer but it does this very quickly. When you start it for the first time, you will see a bare white window with only a search field.

Search Everything is a portable tool that comes with a minimal interface.
