You'll find Sherlock where the "Find File" applet used to be in the Apple Menu, and it doesn't look much different than its predecessor. In addition to the tab that let's you search by the usual group of criteria found in the Find File app, you can also search by content (once you index your hard drive, which can take awhile if you've got a lot of files), and also search the Internet, depending on which Sherlock plug-ins (.src files) are selected.
There are several installed by default, including AltaVista, Infoseek, and Lycos, and bear in mind that the more .src files you have installed (and use) affects Sherlock performance. If you utilize extra search plug-ins, you should increase the app's memory requirements by several hundred K.
Sherlock is very fast, and in the case of Internet searches, pretty thorough too. In fact, we found we can consistently search, sort
and display 5 search engines with Sherlock faster than we can normally search 1 search engine through conventional means. It provides great results, whether you type your query in a formal sentence or question, or use only a couple words or a phrase. Increasingly, we reach for Sherlock as the starting point for our Internet queries rather than jumping to a search engine's web page or portal. There's a certain beauty to having the detailed information you want and need from the Internet, sorted and summarized, neatly delivered to your OS's doorstep. Oh, did we mention that you can save your queries AND your results for later searches? Sherlock is cool technology that works, and works well.
