We spent quite a bit of time with MyLastSearch, and for the life of us, we just can't figure it out. We understand what it's supposed to do; the publisher's description clearly states that it "scans the cache and history files of your Web browser" and returns a list of previous queries made with search engines. Though it does perform this task--to some extent--we couldn't figure out why anyone would use this utility instead of searching within the browser itself.
The program's interface is plain and fairly intuitive by virtue of the fact that it doesn't have many features. It launches and automatically scans the pertinent browser files, returning results in a plain list that includes the search text, search engine, date and time, browser, and URL. It seems straightforward enough, but we were puzzled when MyLastSearch returned only 16 results. That couldn't be right, could it? Had we cleared our browser history recently and forgotten? We checked our history within Firefox and found more than 3,000 search queries made with Google alone. Why didn't MyLastSearch find these? We have no idea. We consulted the Help file that comes with MyLastSearch, but it didn't offer much in the way of assistance. Overall, we see little reason to use MyLastSearch; it doesn't do anything you can't do on your own, and the results it does offer are seriously incomplete.
MyLastSearch is free. The program comes as a ZIP file and operates after extraction with no need for installation. We do not recommend this program.
